156518-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156518-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,1 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156518-69:
(8*1)+(7*5)+(6*6)+(5*5)+(4*1)+(3*8)+(2*6)+(1*9)=153
153 % 10 = 3
So 156518-69-3 is a valid CAS Registry Number.

Synthesis and antiherpetic activity of (Z)- and (E)-9-(3- Phosphonomethoxyprop-1-en-yl)adenines
Ivanov,Andronova,Galegov,Jasko
, p. 58 - 65 (2008/02/01)
The isomeric (Z)- and (E)-9-(3-phosphonomethoxyprop-1-en-yl)adenines were synthesized. The stereoselectivity of double bond formation was studied by variation of sulfonyl groups. The resulting phosphonates exhibited a moderate antiherpetic activity in a c
