Check Digit Verification of cas no

The CAS Registry Mumber 130891-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130891-50:
(8*1)+(7*3)+(6*0)+(5*8)+(4*9)+(3*1)+(2*5)+(1*0)=118
118 % 10 = 8
So 130891-50-8 is a valid CAS Registry Number.

Organophosphorus Chemistry, 18 - The Reaction of 1,8-Naphthosultam with Alkyl Phosphites and Chlorinated Phosphorus Reagents

Abdou, W. M.,Monem, H. A. Abd El,Mahran, M. R.

, p. 1027 - 1031 (2007/10/02)

Trialkyl phosphites (2a-c) react with 1,8-naphthosultam (6) to give the respective N-alkylated products 7a-c.Compounds 7a-c were also prepared by the action of dialkyl phosphites on 6 in the presence of p-TsOH.Moreover, 7a could be obtained by treating 6 with DMMP (8).On the other hand, chlorinated phosphorus reagents (11) condense with 6 to give products of type 12.Structures of the new products were assigned according to consistent analytical and spectroscopic measurements.
