Check Digit Verification of cas no
The CAS Registry Mumber 16681-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,8 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16681-72:
(7*1)+(6*6)+(5*6)+(4*8)+(3*1)+(2*7)+(1*2)=124
124 % 10 = 4
So 16681-72-4 is a valid CAS Registry Number.

Paragraph 0030-0032, (2021/11/19)
The invention discloses 1 - methyl - 1H -1. 2,4 - Triazole -3 - methyl formate preparation method belongs to the technical field of organic synthesis. To 1, 2, 4 - triazole as the raw material, firstly the nucleophilic substitution of methyl 1 -1 and 2 triazole is carried out under the action of a lithium reagent, 4 -position carboxylic acid is obtained by reacting 5-position with carbon dioxide under the action of a non-polar strong base LDA, and 3-position protection is carried out to obtain 3-methyl 3 2, 4 - 5 and 1 -3 - triazole - 1H -1. The invention provides a novel preparation method. Raw materials are easily available, N - methylisomerisation and over quaternization reaction problems are avoided from the source.
