Check Digit Verification of cas no

The CAS Registry Mumber 91396-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,9 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91396-22:
(7*9)+(6*1)+(5*3)+(4*9)+(3*6)+(2*2)+(1*2)=144
144 % 10 = 4
So 91396-22-4 is a valid CAS Registry Number.

Synthesis of 1,3,5-triazinane-2-thiones and 1,3,5-oxadiazinane-4-thiones linked with isoxazoles

Rajanarendar,Siva Rami Reddy,Shaik, Firoz Pasha

experimental part, p. 119 - 122 (2010/04/29)

Trimolecular condensation of N-(3,5-dimethyl-4-isoxazolyl)N′- arylthioureas 2 obtained from 1 by reaction with arylisothiocyanates, with aqueous formaldehyde and primary amines in toluene under reflux leads to 5-alkyl-1-(3,5-dimethyl-4-isoxazolyl)-3-aryl-hexahydro-1,3,5-triazinane-2- thiones 3 in excellent yields. Condensation of 2 with aqueous formaldehyde under similar condition provides isoxazolyl 1,3,5-oxadiazinane-4thiones 4.
