Check Digit Verification of cas no

The CAS Registry Mumber 1256257-81-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1256257-81:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*5)+(3*7)+(2*8)+(1*1)=164
164 % 10 = 4
So 1256257-81-4 is a valid CAS Registry Number.

Highly efficient and practical pyrrolidine-camphor-derived organocatalysts for the direct α-amination of aldehydes

Liu, Pang-Min,Magar, Dhananjay R.,Chen, Kwunmin

experimental part, p. 5705 - 5713 (2011/01/05)

A series of pyrrolidine-camphor-derived organocatalysts (1-4) were designed and synthesised. These organocatalysts were used for direct α-amination of aldehydes with dialkyl azodicarboxylates to give the desired α-aminated products in high chemical yields
