Check Digit Verification of cas no

The CAS Registry Mumber 7009-13-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,0 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7009-13:
(6*7)+(5*0)+(4*0)+(3*9)+(2*1)+(1*3)=74
74 % 10 = 4
So 7009-13-4 is a valid CAS Registry Number.

A simple synthesis of biaryl phospholipase A2 inhibitors: Probing hydrophobic effects

Springer, Dane M.,Bronson, Joanne J.,Mansuri, Muzammil M.,Nettleton, David O.,Tramposch, Kenneth M.

, p. 2669 - 2672 (1996)

A series of biaryl acids has been synthesized by treating diphenic anhydride with a variety of amines. The one step strategy allows the rapid interchange of groups for evaluating the hydrophobic constraints of inhibitors of phopholipase A2. The most active inhibitor synthesized displayed an IC50 = 6 μM against human platelet phospholipase A2.
