Check Digit Verification of cas no

The CAS Registry Mumber 115724-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,7,2 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 115724-85:
(8*1)+(7*1)+(6*5)+(5*7)+(4*2)+(3*4)+(2*8)+(1*5)=121
121 % 10 = 1
So 115724-85-1 is a valid CAS Registry Number.

DIFFERENT MODES OF ALKALINE HYDROLYSIS OF FERVENULIN AND ISOFERVENULIN

Shorshnev, S. V.,Esipov, S. E.,Chernyshev, A. I.,Pozharskii, A. F.,Nanavyan, I. M.,Kuz'menko, V. V.

, p. 1247 - 1251 (1987)

Unlike rheumycin and fervenulin, isofervenulin and 3-methylisofervenulin are hydrolyzed by aqueous alkalies at the N(5)-C(6) bond.On acidification of the reaction mixture, the N-carboxy-N-methylcarbamoyltriazines formed are reconverted into the starting isofervenulins, and on basification (pH > 10) into methylaminotriazinecarboxamides.A by-product of the alkaline hydrolysis of isofervenulin is a product of the contraction of the uracil ring, namely imidazotriazinone-7a-carboxylic acid.
