Check Digit Verification of cas no

The CAS Registry Mumber 1236044-90-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,0,4 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1236044-90:
(9*1)+(8*2)+(7*3)+(6*6)+(5*0)+(4*4)+(3*4)+(2*9)+(1*0)=128
128 % 10 = 8
So 1236044-90-8 is a valid CAS Registry Number.

Novel thiofomylation of primary and secondary amines using N-aryl-1,2,3,4,5,7-pentathiazocanes

Shimada, Kazuaki,Shibuya, Hiroki,Makino, Kenshiro,Otsuka, Tatsuya,Onuma, Yuki,Aoyagi, Shigenobu,Takikawa, Yuji

, p. 1077 - 1089 (2010)

Heating of N-aryl-1,2,3,4,5,7-pentathiazocanes 1 in the presence of primary and secondary amines afforded N-Alkyl or N,N-dialkylthioformamides 5, and similar heating of 1 in the absence of amines afforded an inseparable mixture of acyclic polysulfides 4 bearing a thioformanilide moiety on each terminal. Bisthioformanilides 4 were also converted into 5 by treating with these amines, and the thioformylation was assumed to proceed through a pathway involving the ring fission of 1 and the subsequent nucleophilic attack of these amines onto the thioformyl group of 4.
