Check Digit Verification of cas no

The CAS Registry Mumber 138589-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,8 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138589-87:
(8*1)+(7*3)+(6*8)+(5*5)+(4*8)+(3*9)+(2*8)+(1*7)=184
184 % 10 = 4
So 138589-87-4 is a valid CAS Registry Number.

A Two-Step Synthesis of Diaminofurazan and Synthesis of N-Monoarylmethyl and N,N'-Diarylmethyl Derivatives

Zelenin, Alexander K.,Trudell, Mark L.

, p. 1057 - 1060 (2007/10/03)

Diaminofurazan (1) was synthesized from glyoxal (2) by an improved two-step procedure. The N-monoarylmethyl derivatives 4a-e and N,N'-diarylmethyl derivatives 5a-e of 1 were prepared in good yields by reductive alkylation with the corresponding aryl aldehydes.

Synthesis of 4,8-Disubstituted 4H,8H-Bisoxadiazolopyrazines

Fischer, John W.,Nissan, Robin A.,Lowe-Ma, Charlotte K.
