137676-62-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137676-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,7 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137676-62:
(8*1)+(7*3)+(6*7)+(5*6)+(4*7)+(3*6)+(2*6)+(1*2)=161
161 % 10 = 1
So 137676-62-1 is a valid CAS Registry Number.

DIAZO COMPOUNDS OF THE HETEROCYCLIC SERIES. 4. SOME PECULIARITIES OF THE DIAZO COUPLING OF BENZIMIDAZOLE-2-DIAZONIUM SALTS WITH PHENOLS AND THEIR ETHERS

Kolodyazhnaya, S. N.,Divaeva, L. N.,Sogomonova, R. A.,Simonov, A. M.

, p. 538 - 543 (2007/10/02)

The corresponding hydroxy (methoxy)-substituted azobenzimidazoles were obtained by diazo coupling of benzimidazole-2-diazonium salts with phenols and their complete and incomplete ethers in strongly acidic media; in the case of phenol ethers the process is complicated by dealkylation of the methoxy group in the ortho position relative to the diazo bridge.
