Check Digit Verification of cas no

The CAS Registry Mumber 515132-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,5,1,3 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 515132-84:
(8*5)+(7*1)+(6*5)+(5*1)+(4*3)+(3*2)+(2*8)+(1*4)=120
120 % 10 = 0
So 515132-84-0 is a valid CAS Registry Number.

Domino cyclization of 2-isothiocyanatobenzonitrile with carboxylic hydrazides - One-pot synthesis of 1,2,4-triazolo[1,5-c]quinazoline-5(6H)-thiones

Blank, Janet,Kandt, Madeleine,Pfeiffer, Wolf-Diethard,Hetzheim, Annemarie,Langer, Peter

, p. 182 - 189 (2003)

One-pot reactions between carboxylic hydrazides and 2-isothiocyanatobenzonitrile afforded pharmacologically relevant 1,2,4-triazolo[1,5-c]quinazoline-5(6H)-thiones in good yields. These compounds were transformed into the corresponding amino-substituted derivatives in good yields in one of two steps. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
