Check Digit Verification of cas no
The CAS Registry Mumber 74549-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,4 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74549-14:
(7*7)+(6*4)+(5*5)+(4*4)+(3*9)+(2*1)+(1*4)=147
147 % 10 = 7
So 74549-14-7 is a valid CAS Registry Number.

-
Paragraph 0059; 0064; 0068; 0070; 0072, (2019/01/08)
The present invention provides a process for preparing 4 - acetoxy - 2 - methyl - 2 - butenal new method. Comprises the following steps: 1, fed with methanol reaction to generate acetal thing (I); 2, acetal thing (I) under the catalysis of the copper salt with the peroxide tert-butyl acetate is generated by the reaction (II) shrinks the aldehydo-ester; 3, shrinks the aldehydo-ester (II) hydrolyzed under acidic conditions to obtain 4 - acetoxy - 2 - methyl - 2 - butenal. The method of starting material fed in cheap and easy to obtain, the process route is short, three wastes, synthetic route economic and effective.
