74134-94-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74134-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,3 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74134-94:
(7*7)+(6*4)+(5*1)+(4*3)+(3*4)+(2*9)+(1*4)=124
124 % 10 = 4
So 74134-94-4 is a valid CAS Registry Number.

2-phenyl-1,2,3-osotriazole C-nucleoside analogs synthesis and determination of anomeric configuration
Sallam, Mohammed A.E.
, p. 183 - 186 (1980)
A series of anomeric 2-phenyl-1,2,3-osotriazole C-nucleoside analogs has been prepared. The anomeric configuration was determined by a novel method from the chemical shift of the C-5 proton of the osotriazole base moieties.
