Check Digit Verification of cas no

The CAS Registry Mumber 156498-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,4,9 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 156498-54:
(8*1)+(7*5)+(6*6)+(5*4)+(4*9)+(3*8)+(2*5)+(1*4)=173
173 % 10 = 3
So 156498-54-3 is a valid CAS Registry Number.

Pseudohalogen chemistry. XI. Some aspects of the chemistry of octhiocyanato-β-dicarbonyl compounds

Atkins, Elaine F.,Dabbs, Steven,Guy, Robert G.,Mahomed, Akbar A.,Mountford, Philip

, p. 7253 - 7264 (2007/10/02)

Enolised α-thiocyanato-β-dicarbonyl compounds dimerise in ethanol at room temperature to give tautomeric 4,5-disubstituted 2-amino- and 2-acetamido-thiazoles by a C-S-C + C-N cyclisation. Tautomerism is due to the unusual 4-(β-dicarbonyl-α-thio) substituent. Competing intramolecular cyclisations lead to minor amounts of heterocycles containing the thiazole and/or oxathiole ring systems.
