1269668-50-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1269668-50-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,6,6 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1269668-50:
(9*1)+(8*2)+(7*6)+(6*9)+(5*6)+(4*6)+(3*8)+(2*5)+(1*0)=209
209 % 10 = 9
So 1269668-50-9 is a valid CAS Registry Number.

A highly nucleophilic multifunctional chiral phosphane-catalyzed asymmetric intramolecular rauhut-currier reaction

Zhang, Xiao-Nan,Shi, Min

, p. 6271 - 6279 (2013/01/15)

An asymmetric variant of the intramolecular Rauhut-Currier (RC) reaction can be achieved using a highly nucleophilic multifunctional chiral phosphane; the corresponding cyclopentene and cyclohexene derivatives are produced in moderate to good yields and w

Enantioselective intramolecular Rauhut-Currier reaction catalyzed by chiral phosphinothiourea

Gong, Jing-Jing,Li, Tian-Ze,Pan, Kun,Wu, Xin-Yan

supporting information; experimental part, p. 1491 - 1493 (2011/03/22)

Chiral organophosphine-catalyzed enantioselective Rauhut-Currier reaction has been disclosed for the first time. With l-valine-derived phosphinothiourea, the intramolecular Rauhut-Currier reaction of bis(enones) was achieved in good yields (up to 99%) wit
