Check Digit Verification of cas no
The CAS Registry Mumber 501120-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,1,2 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 501120-42:
(8*5)+(7*0)+(6*1)+(5*1)+(4*2)+(3*0)+(2*4)+(1*2)=69
69 % 10 = 9
So 501120-42-9 is a valid CAS Registry Number.

For structure-activity reasons, an isomeric compound of Viagra, methylated at N-2 at the pyroazolo[4,3-d]pyrimidine-7-one nucleus, was synthesized and its X-ray structure performed. The crystallographic data show that the phenyl and condensed pyrazolo-pyrimidone ring systems are not coplanar to each other.
