Check Digit Verification of cas no

The CAS Registry Mumber 1254364-73-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,3,6 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1254364-73:
(9*1)+(8*2)+(7*5)+(6*4)+(5*3)+(4*6)+(3*4)+(2*7)+(1*3)=152
152 % 10 = 2
So 1254364-73-2 is a valid CAS Registry Number.

The synthesis of paleic acid, an antimicrobial agent effective against Mannheimia and Pasteurella, and its structurally related derivatives

supporting information; experimental part, p. 5843 - 5846 (2010/11/19)

A synthetic route to paleic acid 1, antimicrobial agent effective against Mannheimia haemolytica and Pasteurella multocida, has been established. The absolute configuration of the secondary hydroxyl group was controlled by a catalytic asymmetric alkylation of an aldehyde using a chiral titanium sulfonamide complex and the cis double bond was installed using a Wittig reaction. This synthetic route was also applied to the preparation of structurally related analogs, which were used in structure-activity relationship studies for antibacterial activity.
