Check Digit Verification of cas no

The CAS Registry Mumber 1356856-79-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,8,5 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1356856-79:
(9*1)+(8*3)+(7*5)+(6*6)+(5*8)+(4*5)+(3*6)+(2*7)+(1*9)=205
205 % 10 = 5
So 1356856-79-5 is a valid CAS Registry Number.

METHOD FOR MANUFACTURING OPTICALLY ACTIVE MENTHOL

-

Paragraph 0476; 0477; 0478; 0479, (2013/10/07)

An object of the present invention is to provide a method for manufacturing an optically active menthol having fewer steps, which generates less environmentally polluting waste because a catalytic reaction is involved in all of the steps, and is capable of saving a production cost. The present invention relates to a method for manufacturing an optically active menthol, including the following steps: A-1) asymmetrically hydrogenating at least one of geranial and neral to thereby obtain an optically active citronellal, B-1) conducting a ring-closure reaction of the optically active citronellal in the presence of an acid catalyst to thereby obtain an optically active isopulegol, and C-1) hydrogenating the optically active isopulegol to thereby obtain an optically active menthol.
