83377-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83377-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,7 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83377-49:
(7*8)+(6*3)+(5*3)+(4*7)+(3*7)+(2*4)+(1*9)=155
155 % 10 = 5
So 83377-49-5 is a valid CAS Registry Number.

Improved Synthesis of 2,10-Dioxatricyclo1,6>tetradecanes
Down, Graham J.
, p. 1269 - 1272 (2007/10/02)
Cyanoethylation of substituted cyclohexanones at low temperatures has been found to give markedly improved yields and regioselectivity over the usual conditions for the Michael reaction.This reaction greatly facilitated the preparation of the 2,10-dioxatr
