Check Digit Verification of cas no

The CAS Registry Mumber 178751-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,7,5 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 178751-59:
(8*1)+(7*7)+(6*8)+(5*7)+(4*5)+(3*1)+(2*5)+(1*9)=182
182 % 10 = 2
So 178751-59-2 is a valid CAS Registry Number.

Versatile Synthesis of Enantiomerically Pure 2-Alkoxy-1-ethynylcyclopropanes and Their Application in the Synthesis of Enantiomerically Pure Bicyclo-oct-1-en-3-ones

Braese, Stefan,Schoemenauer, Sten,McGaffin, Gregory,Stolle, Andreas,Meijere, Armin de

, p. 545 - 555 (2007/10/03)

A variety of chiral, nonracemic 2-alkoxy-1-alkynylcylopropanes 7 were synthesized in good to very good yields from enantiomerically pure glycidol derivatives (glycidol tosylate, epichlorohydrin) by boron trifluoride promoted addition of lithium trimethyls
