Check Digit Verification of cas no

The CAS Registry Mumber 135638-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,3 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135638-23:
(8*1)+(7*3)+(6*5)+(5*6)+(4*3)+(3*8)+(2*2)+(1*3)=132
132 % 10 = 2
So 135638-23-2 is a valid CAS Registry Number.

Pheromones, III: A Simple Method to Direct the Reduction of α-Alkoxy-carbonyl Compounds

Noe, Christian R.,Knollmueller, M.,Steinbauer, G.,Wagner, E.,Kuerner, H.,et al.

, p. 299 - 317 (2007/10/02)

Enantiomerically pure 1,2-diols bearing optionally syn or anti configurated secondary hydroxylic groups are synthesized from acetal-protected cyanohydrins.After resolution of the diastereomers the cyanohydrins are converted into α-alkoxy-ketones by Grignard-reaction followed by reduction using common chelating or non-chelating agents.Among others syntheses of enantiomerically pure pheromones, endo-Brevicomin, exo-Brevicomin and Dispalure are given as examples.
