Check Digit Verification of cas no

The CAS Registry Mumber 464189-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,4,1,8 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 464189-36:
(8*4)+(7*6)+(6*4)+(5*1)+(4*8)+(3*9)+(2*3)+(1*6)=174
174 % 10 = 4
So 464189-36-4 is a valid CAS Registry Number.

Highly enantioselective synthesis of chiral imides and derived products via chiral base desymmetrisation

Adams, David J,Blake, Alexander J,Cooke, Paul A,Gill, Christopher D,Simpkins, Nigel S

, p. 4603 - 4615 (2007/10/03)

The enantioselective deprotonation of several ring-fused imides with a chiral base, followed by electrophilic quenching, gives a range of chiral products in good yield and in ≥91% ee. The absolute stereochemistry of two of the products was determined by X-ray crystallography. A number of the imide products were subjected to further, highly regioselective, transformations, including enolate substitution, reduction and thionation.
