Check Digit Verification of cas no

The CAS Registry Mumber 1358909-72-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,8,9,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1358909-72:
(9*1)+(8*3)+(7*5)+(6*8)+(5*9)+(4*0)+(3*9)+(2*7)+(1*2)=204
204 % 10 = 4
So 1358909-72-4 is a valid CAS Registry Number.

A new approach for the synthesis of some pyrazolo [5,1-c]triazines and pyrazolo[1,5-a]pyrimidines containing naphtofuran moiety

Abdelhamid, Abdou O.,Shokry, Shokry A.,Tawfiek, Sayed M.

, p. 116 - 124 (2012/05/05)

Naphtho[2,1-b]furan-2-yl)(8-phenylpyrazolo[5,1-c][1,2,4]triazin-3-yl) methanone, ([1,2,4]triazolo[3, 4-c][1,2,4]triazin-6-yl)(naphtho[2,1-b]furan-2- yl)methanone, benzo[4,5]imidazo[2,1-c][1,2,4]triazin-3-ylnaphtho[ 2,1-b]furan-2-yl-methanone, 5-(naphtho[2,1-b]furan-2-yl)pyrazolo[1,5-a] pyrimidine, 7-(naphtho[ 2,1-b]furan-2-yl)-[1,2,4]triazolo[4,3-a]pyrimidine, 2-naphtho[2,1-b]furan-2-yl-benzo[4,5]imidazo[1, 2-a]pyrimidine, pyridine, and pyrazole derivatives are synthesized from sodium salt of 5-hydroxy-1- naphtho[2,1-b]furan-2-ylpropenone and various reagents. The newly synthesized compounds were elucidated by elemental analysis, spectral data, chemical transformation, and alternative synthetic route whenever possible.
