Check Digit Verification of cas no

The CAS Registry Mumber 316813-66-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,6,8,1 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 316813-66:
(8*3)+(7*1)+(6*6)+(5*8)+(4*1)+(3*3)+(2*6)+(1*6)=138
138 % 10 = 8
So 316813-66-8 is a valid CAS Registry Number.

Synthesis of enantiopure pyrrolidine and piperidine derivatives via ring closing metathesis

Kumareswaran,Balasubramanian,Hassner

, p. 8157 - 8162 (2007/10/03)

The additions of lithiated allylsulfone carbanion to chiral N-sulfinylimines were found to proceed with good to excellent selectivity. The resulting intermediates 4a-d after transformation to dienylamides 7a-d and 16a-d, were converted to functionalized enantiopure piperidines and pyrrolines, respectively, via ring closing metathesis (RCM).
