Check Digit Verification of cas no
The CAS Registry Mumber 28765-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,6 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28765-60:
(7*2)+(6*8)+(5*7)+(4*6)+(3*5)+(2*6)+(1*0)=148
148 % 10 = 8
So 28765-60-8 is a valid CAS Registry Number.

Method for producing N-alkylpiperazine
-
Paragraph 0057, (2017/02/09)
PROBLEM TO BE SOLVED: To provide a method for producing N-alkyl piperazines in high yield by selectively alkylating one amino group.SOLUTION: In the method for producing N-alkyl piperazines, piperazines represented by general formula (1) are reacted with a specific alkylating agent in the presence of an acid. In the formula: R-Rare each independently a hydrogen atom, a methyl group, an ethyl group, a 3-8C linear alkyl group or the like, a hydroxyethyl group, a hydroxypropyl group, a dihydroxypropyl group, a methoxy group, an ethoxy group, a phenyl group, a benzyl group, a 2-phenylethyl group, or the like.
