Check Digit Verification of cas no

The CAS Registry Mumber 90129-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90129-40:
(7*9)+(6*0)+(5*1)+(4*2)+(3*9)+(2*4)+(1*0)=111
111 % 10 = 1
So 90129-40-1 is a valid CAS Registry Number.

Wasabidienone A (WA), a tautomeric mixture of 5-hydroxy-3-methoxy-4,6- dimethyl-(6S)-[(2R)-2-methylbutyryloxy]-cyclohexa-2,4-dien-1-one (1a) and 5- hydroxy-3-methoxy-2,6-dimethyl-(6R)-[(2R)-2-methylbutyryloxy]cyclohexa-2,4- dien-1-one (1b) was synthesized via a novel rearrangement reaction of an acyl group from carbon to the β-hydroxy oxygen on the cyclohexadienone ring. This reaction may occur during fermentation of Phoma wasabiae to form WA from WB1.
