76403-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76403-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,0 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76403-16:
(7*7)+(6*6)+(5*4)+(4*0)+(3*3)+(2*1)+(1*6)=122
122 % 10 = 2
So 76403-16-2 is a valid CAS Registry Number.

An Efficient and General Synthesis of 5-Substituted Pyrrolidinones
Miller, R. D.,Goelitz, P.
, p. 1616 - 1618 (2007/10/02)
2-Pyrrolidinone derivatives are widespread materials of considerable laboratory and commercial importance.In spite of this, there is no generally useful synthesis of either symmetrically or unsymmetrically 5,5-disubstituted derivatives.This is particularl
