10277-53-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10277-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,7 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10277-53:
(7*1)+(6*0)+(5*2)+(4*7)+(3*7)+(2*5)+(1*3)=79
79 % 10 = 9
So 10277-53-9 is a valid CAS Registry Number.

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

Efficient ring-opening reaction of epoxides and aziridines promoted by tributylphosphine in water

Fan, Ren-Hua,Hou, Xue-Long

, p. 726 - 730 (2007/10/03)

Tributylphosphine was found to be an effective promoting reagent for the ring-opening reaction of various epoxides and aziridines with nucleophile to produce corresponding anti-bifunctional products in moderate to excellent yields in water.
