Check Digit Verification of cas no

The CAS Registry Mumber 1555-67-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1555-67:
(6*1)+(5*5)+(4*5)+(3*5)+(2*6)+(1*7)=85
85 % 10 = 5
So 1555-67-5 is a valid CAS Registry Number.

OBSERVATIONS ON THE VILSMEIER REACTION Part 2. THE ANOMALOUS REACTION OF N-BENZYL N-CYANOETHYL-4-METHYLANILINE DERIVATIVES

Shawcross, Andrew P.,Stanforth, Stephen P.

, p. 7063 - 7076 (2007/10/02)

The reaction of a series of the title anilines (1) with variously substituted benzyl groups under Vilsmeier conditions was invesigated.Only perfluorobenzyl derivatives showed normal formylation while other fluoro derivatives gave mixed results and other substituents gave solely the anomalous amine (5) together with the aldehyde (6) derived from the benzyl group.
