Check Digit Verification of cas no

The CAS Registry Mumber 188657-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,5 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188657-83:
(8*1)+(7*8)+(6*8)+(5*6)+(4*5)+(3*7)+(2*8)+(1*3)=202
202 % 10 = 2
So 188657-83-2 is a valid CAS Registry Number.

Chemoenzymatic studies: From cycloheptatriene to the core of zaragozic acids

Xu, Yanping,Johnson, Carl R.

, p. 1117 - 1120 (1997)

(1R,4S,6S)-4-Acetoxy-6-triisopropylsilyl prepared from cycloheptatriene utilizing an asymmetrization of the precursor diol with Candida antarctica lipase B/isopropenyl acetate, was converted to (1S,3R,4S,5S,6R,7R)-4,6,7-triacetoxy-5-benzyloxymethyl-4-acetoxymethyl-2,8 -dioxabicyclo[3.2.1]octane representing,the core of zaragozic acid by a strategy involving Rubottom oxidations and ozonolysis.
