Check Digit Verification of cas no

The CAS Registry Mumber 14032-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,3 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 14032-04:
(7*1)+(6*4)+(5*0)+(4*3)+(3*2)+(2*0)+(1*4)=53
53 % 10 = 3
So 14032-04-3 is a valid CAS Registry Number.

Synthesis and application of Cu(II) immobilized MCM-41 based solid Lewis acid catalyst for aminolysis reaction under solvent-free condition

Chaudhary, Garima,Gupta, Neha,Singh, Amit Pratap

supporting information, (2021/07/22)

In this paper, a Cu(II) immobilized periodic mesoporous organosilica (PMOs) was synthesized and used as a reusable solid Lewis acid catalyst for the aminolysis of epoxides under solvent-free conditions. An amide-based ligand, L-propylsilyl (1) having a specific binding pocket was prepared and fabricated on mesoporous MCM-41 to produce mesoporous organosilica L-propylsilyl@MCM-41 (2). Further, it has been utilized for anchoring Cu(II) ions under controlled reaction conditions to yield solid Lewis acid catalyst Cu(II)-L-propylsilyl@MCM-41 (3). The synthesized catalyst 3 exhibits significantly higher catalytic activity for aminolysis compared to hitherto known solid Lewis acid catalysts. An extensive range of β-amino alcohols with high regio and stereoselectivity were prepared by using catalyst 3. The catalyst was recovered easily and reused eight times without any loss in its catalytic activity. Furthermore, the synthesis of clinically significant propranolol (β-blocker) from α- naphthyl glycidyl ether was attained successfully using catalyst 3 in a very decent yield.

Rapid, benign, and additive-free thiolysis of epoxides under ultrasonic/aqueous conditions

Mojtahedi, Mohammad M.,Khalili, Sajad

, p. 431 - 437 (2014/06/10)

An environmentally friendly and efficient procedure is developed for ring opening of various epoxides with thiols under non-thermal conditions. Reactions take place by ultrasonic irradiation of the two reactants suspended in an additive-free aqueous mediu

Highly enantioselective kinetic resolution of trans-2-(phenylthio) cyclohexanol derivatives by immobilized Candida antartica B lipase

Chimni, Swapandeep Singh,Kaur, Kirandeep,Bala, Neeraj

, p. 67 - 74 (2013/10/22)

Candida antartica B (immobilized CAL-B) mediated resolutions of trans-2-(phenylthio)cyclohexanol derivatives using vinyl acetate as acylating agent and MTBE as solvent provide excellent enantioselectivity (up to >99%) and high yield of both the enantiomer
