73977-65-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73977-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,7 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73977-65:
(7*7)+(6*3)+(5*9)+(4*7)+(3*7)+(2*6)+(1*5)=178
178 % 10 = 8
So 73977-65-8 is a valid CAS Registry Number.

N-Alkylation of Cytosine and Its Nucleosides with Trialkyl Phosphates
Hayashi, Masahiro,Yamauchi, Kiyoshi,Kinoshita, Masayoshi
, p. 277 - 278 (2007/10/02)
Cytosine has been readily alkylated with trialkyl phosphates to give the corresponding N-alkyl derivatives, trimethyl phosphate being especially useful for the N-methylation of the base moiety of cytosine nucleosides.
