Check Digit Verification of cas no

The CAS Registry Mumber 400869-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,8,6 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 400869-07:
(8*4)+(7*0)+(6*0)+(5*8)+(4*6)+(3*9)+(2*0)+(1*7)=130
130 % 10 = 0
So 400869-07-0 is a valid CAS Registry Number.

A regioselective addition of nucleophiles to monocyclic 1,2-thiazinylium perchlorate: A novel precursor of 6-substituted 1,2-thiazines

Shimizu, Hiroshi,Okada, Naoyuki,Yoshimatsu, Mitsuhiro

, p. 8965 - 8969 (2007/10/03)

The nucleophilic addition reactions of 4,5-diphenyl-1,2-thiazinylium perchlorate 1 regioselectively proceeded to give 6-alkoxy-3a-c and 6-alkyl-1,2-thiazines 3e-f, 4f, 3i-j in good to high yields. The Friedel-Crafts type reaction with arenes also afforded 6-aryl adducts 6a-c.
