Check Digit Verification of cas no

The CAS Registry Mumber 132440-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,4 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132440-30:
(8*1)+(7*3)+(6*2)+(5*4)+(4*4)+(3*0)+(2*3)+(1*0)=83
83 % 10 = 3
So 132440-30-3 is a valid CAS Registry Number.

Stereoselective Synthesis of Terminal 1,3-Butadienes by the Condensation Reaction of Aldehydes and Ketones with the γ-Trimethylsilyl-Substituted Allylboranes

Wang, Kung K.,Liu, Chin,Gu, Yu Gui,Burnett, Friedrich N.,Sattsangi, Prem D.

, p. 1914 - 1922 (1991)

Allylboranes 7-12, readily prepared from allenylsilanes 1-6 by hydroboration with 9-borabicyclononane, smoothly condense with aldehydes and ketones to afford, after basic or acidic workup to promote the Peterson olefination reaction, a variety of t
