Check Digit Verification of cas no

The CAS Registry Mumber 1185774-42-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,7,7 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1185774-42:
(9*1)+(8*1)+(7*8)+(6*5)+(5*7)+(4*7)+(3*4)+(2*4)+(1*2)=188
188 % 10 = 8
So 1185774-42-8 is a valid CAS Registry Number.

Highly enantioselective and organocatalytic α-amination of 2-Oxindoles

Cheng, Liang,Liu, Li,Wang, Dong,Chen, Yong-Jun

supporting information; experimental part, p. 3874 - 3877 (2009/12/06)

Figur Presented An effective method for the asymmetric synthesis of 3-amino-2-oxindoles was developed. The tetrasubstituted chiral carbon center was generated by asymmetric amination of N-unprotected 2-oxindoles with azodicarboxylate catalyzed by commercial biscinchona alkaloids in good to excellent yields with high enantioselectivities.
