Check Digit Verification of cas no

The CAS Registry Mumber 1207680-81-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,6,8 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1207680-81:
(9*1)+(8*2)+(7*0)+(6*7)+(5*6)+(4*8)+(3*0)+(2*8)+(1*1)=146
146 % 10 = 6
So 1207680-81-6 is a valid CAS Registry Number.

C-amidoalkylation of pyrroles with N-trifluoromethylsulfonyl and N-arylsulfonyl polychloroaldehyde imines

Kondrashov,Rudyakova,Rozentsveig,Rozentsveig,Chernyshev,Krivdin,Levkovskaya

experimental part, p. 1365 - 1374 (2010/01/11)

N-(Trifluoromethylsulfonyl) and N-arylsulfonyl polychloroacetaldehyde imines reacted with pyrrole, 1-alkyl-, 1-benzyl-, and 1-(4-nitrophenyl)- substituted pyrroles, and bis-pyrroles to give the corresponding 2-[1-(sulfonylamino)polychloroethyl]-1H-pyrroles or mixtures of 2- and 3-[1-(sulfonylamino)polychloroethyl]-1H-pyrroles, depending on the nature of the Schiff base and substituent on the pyrrole nitrogen atom and reaction conditions. The first synthesis of 2,5-disubstituted NH-pyrrole by reaction of pyrrole with Schiff bases was described.
