Check Digit Verification of cas no

The CAS Registry Mumber 215673-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,6,7 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 215673-95:
(8*2)+(7*1)+(6*5)+(5*6)+(4*7)+(3*3)+(2*9)+(1*5)=143
143 % 10 = 3
So 215673-95-3 is a valid CAS Registry Number.

Novel intramolecular cyclization reaction involving a thionitroso group: Formation of a 3,3a-dihydro-2,1-benzisothiazole from an o-alkylthionitrosoarene

Tan, Bo,Goto, Kei,Kobayashi, Junji,Okazaki, Renji

, p. 981 - 982 (2007/10/03)

A thionitrosoarene generated by the desulfurization reaction of a stable N-thiosulfinylaniline bearing a bowl-type substituent underwent the intramolecular cyclization reaction involving the ortho-alkyl group to afford the corresponding 3,3a-dihydro-2,1-benzisothiazole. The intermediacy of the thionitrosoarene was corroborated by a trapping experiment with aniline.
