Check Digit Verification of cas no

The CAS Registry Mumber 195525-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,5,2 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 195525-48:
(8*1)+(7*9)+(6*5)+(5*5)+(4*2)+(3*5)+(2*4)+(1*8)=165
165 % 10 = 5
So 195525-48-5 is a valid CAS Registry Number.

Pyrrolidinones derived from (S)-pyroglutamic acid. Part 3. β-Aminopyrrolidinones

Chan,Cottrell,Moloney

, p. 2997 - 3006 (2007/10/03)

The conjugate addition of activated nitrogen nucleophiles, such as hydroxylamine and hydrazine derivatives, to α, β-unsaturated bicyclic lactam 1a gave the corresponding β-amino products 9a-g in good yield and excellent diastereo- selectivity. These products can be manipulated to afford enantiopure β-aminopyrrolidinones of potential application as conformationally-constrained, substituted glutamate templates of well-defined stereochemistry.
