39668-33-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39668-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,6,6 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 39668-33:
(7*3)+(6*9)+(5*6)+(4*6)+(3*8)+(2*3)+(1*3)=162
162 % 10 = 2
So 39668-33-2 is a valid CAS Registry Number.

Preparation method of vitamin A and vitamin A ester

-

, (2020/04/02)

The invention provides a novel method for preparing vitamin A and vitamin A ester with farnesene as a raw material. The method comprises the following steps: reacting farnesene with acetoacetate underthe action of a catalyst to obtain farnesyl keto ester; carrying out a cyclization reaction and a dehydrogenation reaction on farnesene acetone, and then reacting a reaction product with vinyl magnesium halide to generate vinyl alcohol; carrying out a rearrangement reaction on vinyl alcohol to obtain vitamin A; and subjecting the vitamin A to an esterification reaction to obtain the vitamin A ester. The method avoids the defects of the existing processes, and the process line of the method is economical and effective.
