Check Digit Verification of cas no

The CAS Registry Mumber 139141-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,4 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139141-20:
(8*1)+(7*3)+(6*9)+(5*1)+(4*4)+(3*1)+(2*2)+(1*0)=111
111 % 10 = 1
So 139141-20-1 is a valid CAS Registry Number.

Synthesis of new ether glycerophospholipids structurally related to modulator

Garcia,Pascual,Borras,Andreu,Fos,Mauleon,Carganico,Arcamone

, p. 10023 - 10034 (2007/10/02)

A series of new glycerophospholipids, bearing a short-chain carboxylic acid in position sn-1 and phosphocholine or phosphoserine in postion sn-3 of glycerol, have been prepared in good overall yields. Compound 11, 1-0-(6-carboxyhexyl)-sn-glycero-3-phosphoserine, a strict analog of the structure proposed for modulator, has been synthesized in a stereoselective way from (R)-1,2-isopropylideneglycerol 1.
