83236-57-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83236-57-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,3 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83236-57:
(7*8)+(6*3)+(5*2)+(4*3)+(3*6)+(2*5)+(1*7)=131
131 % 10 = 1
So 83236-57-1 is a valid CAS Registry Number.

Koblik, A. V.,Suzdalev, K. F.,Loktionov, A. A.
, p. 155 - 161 (2007/10/02)
Synthesis of 1-benzoxepines by dehydrochlorination of carbene adducts of chromenes has been carried out.Different alkyl-, alkylidene-, alkoxy-, aryl- and hetarylsubstituted 1-benzoxepines were obtained.
