Check Digit Verification of cas no

The CAS Registry Mumber 1453869-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,8,6 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1453869-57:
(9*1)+(8*4)+(7*5)+(6*3)+(5*8)+(4*6)+(3*9)+(2*5)+(1*7)=202
202 % 10 = 2
So 1453869-57-2 is a valid CAS Registry Number.

Synthesis and biological activity of novel diphenyl N - Substituted Carbamimidoylphosphoramidate derivatives

Subramanyam,Ramana, K. Venkata,Rasheed,Adam,Raju, C. Naga

, p. 1228 - 1235 (2013/09/23)

An efficient synthesis of a series of novel diphenyl N-substituted carbamimidoyl phosphoramidate derivatives was accomplished in two steps. Diphenyl phosphorochloridate (1) was reacted with cyanamide (2) in the presence of 1,4-dimethylpiperazine as a base in THF at 50-55 °C to form an intermediate, diphenyl cyanophosphoramidate (3). Subsequently 3 was reacted with various aromatic/heterocyclic amines (4) in the presence of 1,4-dimethyl piperazine as a base at 55-60 °C to form the corresponding title compounds 5(a-k). The title compounds were tested for antiviral activity against Tobacco mosaic virus (TMV) in vitro, antibacterial and antifungal activities at two different concentrations of 50 and 100 μg/mL. The title compounds exhibited good antiviral and antimicrobial activities when compared to the standards.
