343776-92-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 343776-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,7,7 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 343776-92:
(8*3)+(7*4)+(6*3)+(5*7)+(4*7)+(3*6)+(2*9)+(1*2)=171
171 % 10 = 1
So 343776-92-1 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
