228556-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228556-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,5,5 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228556-52:
(8*2)+(7*2)+(6*8)+(5*5)+(4*5)+(3*6)+(2*5)+(1*2)=153
153 % 10 = 3
So 228556-52-3 is a valid CAS Registry Number.

THE SYNTHESES OF (R)-(+)-β-VANILLYL-γ-BUTYROLACTONE AND OF CHIRAL LIGNANS THEREFROM
Brown, Eric,Daugan, Alain
, p. 1169 - 1172 (2007/10/02)
(R)-(+)-β-vanillyl-γ-butyrolactone was obtained in 4 steps including a resolution, from vanillin and dimethyl succinate, and was used for the total syntheses of 5 naturally occurring and optically active lignans such as (+)-isolariciresinol 20.
