Check Digit Verification of cas no

The CAS Registry Mumber 117940-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,4 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117940-44:
(8*1)+(7*1)+(6*7)+(5*9)+(4*4)+(3*0)+(2*4)+(1*4)=130
130 % 10 = 0
So 117940-44-0 is a valid CAS Registry Number.

Convenient Syntheses of Optically Active Abscisic Acid and Xanthoxin

Sakai, Kunikazu,Takahashi, Kyoko,Nukano, Tomoko

, p. 8229 - 8239 (2007/10/02)

The Reformatzky reaction of 3-(bromomethyl)crotonate with an optically active epoxycyclohexane aldehyde derivative (3), followed by dehydration, gave the chiral dienoic acid (6) stereospecifically.The product was derived to optically active abscisic acid (1) and xanthoxin (2) successfully.
