Check Digit Verification of cas no

The CAS Registry Mumber 1252759-81-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,7,5 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1252759-81:
(9*1)+(8*2)+(7*5)+(6*2)+(5*7)+(4*5)+(3*9)+(2*8)+(1*1)=171
171 % 10 = 1
So 1252759-81-1 is a valid CAS Registry Number.

Functionalized chiral ionic liquid catalyzed asymmetric SN1 α-alkylation of ketones and aldehydes

Zhang, Long,Cui, Lingyun,Li, Xin,Li, Jiuyuan,Luo, Sanzhong,Cheng, Jin-Pei

experimental part, p. 4876 - 4885 (2010/10/04)

Pyrrolidine-derived functionalized chiral ionic liquids (FCILs) have been found to catalyze asymmetric SN1 α-alkyl-ations of ketones and aldehydes with up to 99% yield, >99:1 dr and 87% ee. The FCIL catalysts enable SN1 α-alkylations
