Check Digit Verification of cas no

The CAS Registry Mumber 136712-88-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,1 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136712-88:
(8*1)+(7*3)+(6*6)+(5*7)+(4*1)+(3*2)+(2*8)+(1*8)=134
134 % 10 = 4
So 136712-88-4 is a valid CAS Registry Number.

Reissert Compound Formation with Fused Five-Membered Ring Heterocycles

Uff, Barrie C.,Ho, Yee-Ping,Brown, David S.,Fisher, Ian,Popp, Frank D.,Kant, Joydeep

, p. 2652 - 2681 (2007/10/02)

Reissert compounds have been prepared in high yield from benzothiazole by use of trimethylsilyl cyanide as source of cyanide in a single phase system.Analogues have been made from benzoxazole, indazole and 1-methylindazole but the method was unsuccessful with 1,2-benzisoxazole and pyrazole.Conjugate base alkylation followed by removal of the Reissert grouping provides a route to 2-alkylbenzothiazoles and -benzoxazoles, and 3-alkylated indazoles.Efficient access to pyridobenzothiazole and benzothiazoloisoquinoline derivatives results from appropriate intramolecular cyclisations.A crystal structure determination of 3-benzoyl-2,3-dihydro-2-benzothiazolecarbonitrile is reported.
