Check Digit Verification of cas no

The CAS Registry Mumber 1429218-17-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,9,2,1 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1429218-17:
(9*1)+(8*4)+(7*2)+(6*9)+(5*2)+(4*1)+(3*8)+(2*1)+(1*7)=156
156 % 10 = 6
So 1429218-17-6 is a valid CAS Registry Number.

Tandem ring-closing metathesis/isomerization reactions for the total synthesis of violacein

Petersen, Mette T.,Nielsen, Thomas E.

supporting information, p. 1986 - 1989 (2013/06/05)

A series of 5-substituted 2-pyrrolidinones was synthesized through a one-pot ruthenium alkylidene-catalyzed tandem RCM/isomerization/nucleophilic addition sequence. The intermediates resulting from RCM/isomerization showed reactivity toward electrophiles in aldol condensation reactions which provided a new entry for the total synthesis of the antileukemic natural product violacein.
