Check Digit Verification of cas no

The CAS Registry Mumber 220337-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,3 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220337-13:
(8*2)+(7*2)+(6*0)+(5*3)+(4*3)+(3*7)+(2*1)+(1*3)=83
83 % 10 = 3
So 220337-13-3 is a valid CAS Registry Number.

Addition of 1-Boc-2-tert-butyldimethylsilyloxypyrrole to N- methyleneamine equivalents: Synthesis of 1-Boc-5-aminomethyl-2,5- dihydropyrrol-2-ones and 1-Boc-2-oxo-1,7,9-triazaspiro[4,5]dec-3-enes

, p. 203 - 214 (1999)

N-Methyleneamine equivalents generated from 1,3,5-triphenylhexahydro- 1,3,5-triazines or N-methoxymethylanilines reacted with 1-Boc-2- tertbutyldimethylsilyloxypyrrole to give 1-Boc-5-anilinomethyl-2,5- dihydropyrrol-2-ones. However, the same reaction from 1,3,5- trialkylhexahydro-1,3,5-triazines yielded unexpected product of 1-Boc-7,9- dialkyl-2-oxo-1,7,9-triazaspiro[4,5]dec-3-enes.
