Check Digit Verification of cas no
The CAS Registry Mumber 313481-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,4,8 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 313481-56:
(8*3)+(7*1)+(6*3)+(5*4)+(4*8)+(3*1)+(2*5)+(1*6)=120
120 % 10 = 0
So 313481-56-0 is a valid CAS Registry Number.

, p. 999 - 1004 (2005)
It has been shown that amino derivatives of sulfanilamide, and also some functionally substituted primary arylamines and cycloalkylamines, undergo heterocyclization with triethyl orthoformate and sodium azide with the formation of 1-monosubstituted tetraz
