Check Digit Verification of cas no

The CAS Registry Mumber 76892-11-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,9 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76892-11:
(7*7)+(6*6)+(5*8)+(4*9)+(3*2)+(2*1)+(1*1)=170
170 % 10 = 0
So 76892-11-0 is a valid CAS Registry Number.

PYRROLES FROM KETOXIMES AND ACETYLENE. 24. ACIDIC HYDROLYSIS OF 1-VINYLPYRROLES

Trofimov, B.A.,Korostova, S.E.,Mikhaleva, A.I.,Sobenina, L.N.,Vasil'ev, A.N.

, p. 1257 - 1265 (1982)

The hydrolysis of 2-methyl-, 2-phenyl-, and 3-methyl-2-phenyl-1-vinylpyrroles and 1-vinyl-4,5,6,7-tetrahydroindole in the presence of HCl, H2SO4, NH2OH*HCl, acetic acid, and H2O2 in aqueous, aqueous dioxane, and aqueous alcohol solutions leads to oligomers with complex structures and compositions, viz., products of acidic catalytic and oxidative condensation of the starting compounds and the resulting pyrroles both with one another and with the liberated acetaldehyde. 2-Phenylpyrrole was obtained in 52percent yield from 1-vinyl-2-phenylpyrrole by hydrolysis in a dilute (0.5percent) solution with excess NH2OH*HCl, which ties up the acetaldehyde.
