Check Digit Verification of cas no

The CAS Registry Mumber 21892-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,9 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21892-80:
(7*2)+(6*1)+(5*8)+(4*9)+(3*2)+(2*8)+(1*0)=118
118 % 10 = 8
So 21892-80-8 is a valid CAS Registry Number.

Carbonylation of o-phenylenediamine and o-aminophenol with dimethyl carbonate using lead compounds as catalysts

Fu, Yue,Baba, Toshihide,Ono, Yoshio

, p. 91 - 97 (2007/10/03)

Lead compounds are active catalysts for carbonylation and carbonylation/methylation of o-phenylenediamine and o-aminophenol with dimethyl carbonate (DMC). 2-Benzimidazolone was obtained in 84% yield by the reaction of o-phenylenediamine with DMC for 1 h at 443 K in the presence of Pb(NO3)2. In the presence of Pb(OAc)2, the reaction quantitatively gave 1,3-dimethyl-2-benzimidazolone, which was formed by methylation of the primary product, 2-benzimidazolone, at 473 K. The effects of reaction variables on the yields of 2-benzimidazolone and 1,3-dimethyl-2-benzimidazolone were examined. The reaction of o-aminophenol with DMC selectively gave a carbonylation product, 2-benzoxazolone, or a carbonylation/methylation product, 3-methyl-2-benzoxazolone, depending on the reaction conditions in the presence of Pb(OAc)2.
