Check Digit Verification of cas no

The CAS Registry Mumber 75040-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,4 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75040-58:
(7*7)+(6*5)+(5*0)+(4*4)+(3*0)+(2*5)+(1*8)=113
113 % 10 = 3
So 75040-58-3 is a valid CAS Registry Number.

Heterocyclic Prostaglandin Analogues. Part 2. Hydantoins and Other Imidazole Analogues

Caldwell, A. Gordon,Harris, C. John,Stepney, Ray,Whittaker, Norman

, p. 495 - 505 (2007/10/02)

The stable hydantoin prostaglandin analogues (2b) and (3b) have been synthesised as racemic compounds.The less polar diastereoisomer of (2b) is a potent inhibitor of platelet aggregation in human platelet-rich plasma and its cyclohexyl analogue (22, R = C6H11) has ca. 14 times the potency of prostaglandin E1 in this test coupled with selectivity of biological action.Other structural modifications such as introduction of a 15-methyl group and insertion of the m-phenylene or m-oxaphenylene moieties into the acid side-chain of (2b) led to a reduction in anti-aggregatory potency.Synthesis of the imidazole (41) is described.
