Check Digit Verification of cas no

The CAS Registry Mumber 77617-14-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,1 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77617-14:
(7*7)+(6*7)+(5*6)+(4*1)+(3*7)+(2*1)+(1*4)=152
152 % 10 = 2
So 77617-14-2 is a valid CAS Registry Number.

Novel method for producing 2-amino-1, 3-propylene glycol by JIT method

-

Paragraph 0042-0047, (2021/11/26)

The invention belongs to the field of fine chemical engineering, and relates to a novel method for producing 2-amino-1, 3-propylene glycol by a JIT method, the novel method is composed of a catalytic chlorination reaction and a catalytic amination reaction, glycerol is chlorinated by hydrogen chloride under the catalysis of zinc chloride to obtain 2-chloro-1, 3-propylene glycol, and the 2-chloro-1, 3-propylene glycol is subjected to a catalytic reaction by urotropin to obtain 2-chloro-1, 3-propylene glycol.
