Check Digit Verification of cas no

The CAS Registry Mumber 78033-95-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,3 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78033-95:
(7*7)+(6*8)+(5*0)+(4*3)+(3*3)+(2*9)+(1*5)=141
141 % 10 = 1
So 78033-95-1 is a valid CAS Registry Number.

FUNCTIONAL DERIVATIVES OF THIOPHENE. 18. SYNTHESIS OF 4-OXOTHIENOOXAZINE DERIVATIVES AND THIOPHENE-3-CARBOXYLIC ACID HYDRAZIDES

Kharizomenova, I.A.,Samsonova, N.V.,Kaplina, N.V.,Kapustina, M.V.,Grinev, A.N.

, p. 36 - 37 (1980)

2-Aryl-4-oxothienooxazine derivatives were synthesized.Opening of the oxazine ring to give 2-benzamidothiophene-3-carboxylic acid hydrazide derivatives is observed when these compounds are treated with hydrazine hydrate.
