Check Digit Verification of cas no
The CAS Registry Mumber 113722-25-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,7,2 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 113722-25:
(8*1)+(7*1)+(6*3)+(5*7)+(4*2)+(3*2)+(2*2)+(1*5)=91
91 % 10 = 1
So 113722-25-1 is a valid CAS Registry Number.

The isomeric compositions of the products of nitration of 2-methylcoumaran and chroman with acetyl nitrate were determined.More convenient methods for the synhtesis of 7-amino-2-methylcoumaran and 8-aminochroman were developed, and 9-amino-1-benzoxepane was obtained for the first time.Alkylaminoacylaminosubstituted 2-methylcoumarans, chromans, and 1-benzoxepanes were synthesized.A method for the synthesis of 2-bromocaproyl chloride from caproic acid was developed.
