Check Digit Verification of cas no

The CAS Registry Mumber 180297-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,2,9 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 180297-89:
(8*1)+(7*8)+(6*0)+(5*2)+(4*9)+(3*7)+(2*8)+(1*9)=156
156 % 10 = 6
So 180297-89-6 is a valid CAS Registry Number.

Synthesis of novel vitamin C phosphodiesters: Stability and antioxidant activity

Morisaki, Kazuo,Ozaki, Shoichiro

, p. 123 - 138 (2007/10/03)

A novel series of hybrid L-ascorbic acid (vitamin C) phosphodiesters linked at the C-2 hydroxyl group with other biologically active substances, namely myo-inositol, arbutin, 4-hydroxy-L-proline, and glycolic acid were synthesized, and their thermal stability and reducing activity against free radicals were estimated in vitro. All of the phosphodiesters exhibited high thermal stabilities; however, their antioxidant activities in vitro were generally lower than that of vitamin C.
