Check Digit Verification of cas no

The CAS Registry Mumber 220239-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,3 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220239-33:
(8*2)+(7*2)+(6*0)+(5*2)+(4*3)+(3*9)+(2*3)+(1*3)=88
88 % 10 = 8
So 220239-33-8 is a valid CAS Registry Number.

Sodium borohydride-iodine mediated reduction of γ-lactam carboxylic acids followed by DDQ mediated oxidative aromatisation: a simple approach towards N-aryl-formylpyrroles and 1,3-diaryl-formylpyrroles

Haldar, Pranab,Barman, Gopa,Ray, Jayanta K.

, p. 3049 - 3056 (2007)

A simple methodology for the conversion of substituted N-aryl-γ-lactam 2/3-carboxylic acids to substituted N-aryl-2/3-formyl-pyrroles has been developed. Several N-aryl-γ-lactam 2/3-carboxylic acids were reduced to substituted (N-aryl-pyrroliden-2/3-yl)-m
