Check Digit Verification of cas no

The CAS Registry Mumber 1420790-89-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,7,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1420790-89:
(9*1)+(8*4)+(7*2)+(6*0)+(5*7)+(4*9)+(3*0)+(2*8)+(1*9)=151
151 % 10 = 1
So 1420790-89-1 is a valid CAS Registry Number.

PROCESS FOR PREPARATION OF PROSTAGLANDIN F2 ALPHA ANALOGUES

-

Paragraph 0231; 0232, (2015/02/19)

A convergent synthesis of the prostaglandin F2α analogues, travoprost and bimatoprost, was developed employing Julia-Lythgoe olefination of the structurally advanced phenylsulfone with an enantiomerically pure aldehyde ω-chain synthon. The novel convergent strategy allows the synthesis of a whole series of prostaglandin analogues of high purity from a common and structurally advanced prostaglandin intermediate.
