1331960-87-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1331960-87-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,1,9,6 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1331960-87:
(9*1)+(8*3)+(7*3)+(6*1)+(5*9)+(4*6)+(3*0)+(2*8)+(1*7)=152
152 % 10 = 2
So 1331960-87-2 is a valid CAS Registry Number.

Abdel-Hafez,Abdel-Monem,Mohamed,Abdelrazek,Metwally
, p. 363 - 370 (2011/12/04)
New series of selenolo[2,3-c]pyridazine and pyrimido[4′,5′:4,5] selenolo[2,3-c]pyridazine derivatives were prepared from 4-cyano-5,6- diphenylpyridazine-3(2H)-selenone. Elemental analysis, IR, 1H NMR, and mass spectra confirmed the structures o
