777092-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 777092-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,7,0,9 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 777092-55:
(8*7)+(7*7)+(6*7)+(5*0)+(4*9)+(3*2)+(2*5)+(1*5)=204
204 % 10 = 4
So 777092-55-4 is a valid CAS Registry Number.

Diphenylmethyl protective group in the synthesis of 5-substituted 3-nitro-1H-1,2,4-triazoles
Tolstyakov,Tselinskii
, p. 399 - 404 (2007/10/03)
A diphenylmethyl protective group is suggested for use in the synthesis of 5-R-3-nitro-1H-1,2,4-triazoles unsubstituted at the cyclic nitrogen atom, via nucleophilic substitution of 5-bromo- and 5-methylsulfonyl groups.
