Check Digit Verification of cas no

The CAS Registry Mumber 132373-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,3,7 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132373-06:
(8*1)+(7*3)+(6*2)+(5*3)+(4*7)+(3*3)+(2*0)+(1*6)=99
99 % 10 = 9
So 132373-06-9 is a valid CAS Registry Number.

REACTION OF CARBAMOYL DERIVATIVES OF 4- AND 5-HYDROXYLAMINOTHIAZOLIDINE-2-THIONES AND 4-HYDROXYLAMINOIMIDAZOLIDIN-2-ONE WITH METHYL CHLOROFORMATE. PROPERTIES OF SUBSTITUTED 1,2,4-OXADIAZOLIDINE-3,5-DIONES.

Acylation with methyl chloroformate of N-monocarbamoyl derivatives of 4- and 5-hydroxylaminothiazolidin-2-thione and 4-hydroxylaminoimidazolidin-2-one, depending on their structure and the reaction conditions, leads either to N,O-bisacylhydroxylamines or to their intramolecular cyclization products, the substituted 1,2,4-oxadiazolidine-3,5-diones which, on decarboxylation, may convert into the corresponding 4- and 5-carbamoyliminothiazolidine-2-thiones.
