Check Digit Verification of cas no
The CAS Registry Mumber 19780-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,8 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19780-56:
(7*1)+(6*9)+(5*7)+(4*8)+(3*0)+(2*5)+(1*6)=144
144 % 10 = 4
So 19780-56-4 is a valid CAS Registry Number.

Protium-deuterium exchange of cyclic and acyclic alkanens in dilute acid medium at elevated temperatures
Werstiuk, Nick Henry,Timmins, George
, p. 530 - 533 (2007/10/02)
A modification of the high temperature - dilute acid (HTDA) method for deuterium labelling of aromatic compounds has been applied to the H-D exchange of a number of cyclic and acyclic alkenes.Cyclopentene, cyclohexene, cyclododecene, and tetramethylethylene have been completely exchanged in excellent yield. 1-Methylcyclopentene and 1-methylcyclohexene have also been perdeuterated and cycloheptene and cyclooctene partially labelled but require spinning band distillation or preparative glpc for separation from rearrangement products.A variety of C5-C8 acyclic alkeneshave also been treated under HTDA conditions.
