1355731-09-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1355731-09-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,5,7,3 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1355731-09:
(9*1)+(8*3)+(7*5)+(6*5)+(5*7)+(4*3)+(3*1)+(2*0)+(1*9)=157
157 % 10 = 7
So 1355731-09-7 is a valid CAS Registry Number.

Chiral pyrrolidine quaternary derivatives as organocatalysts for asymmetric Michael additions
Sun, Huichao,Wang, Ge,Yan, Xilong,Chen, Ligong
, p. 1501 - 1509 (2012)
A series of chiral pyrrolidine quaternary derivatives were designed and synthesized. It was found that these derivatives are highly efficient organocatalysts for the asymmetric Michael addition reactions of aldehydes and ketones to nitroolefins with high
