Check Digit Verification of cas no
The CAS Registry Mumber 31645-84-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,6,4 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 31645-84:
(7*3)+(6*1)+(5*6)+(4*4)+(3*5)+(2*8)+(1*4)=108
108 % 10 = 8
So 31645-84-8 is a valid CAS Registry Number.

The use of 1,4-dichlorobut-2-ene as a synthetic equivalent of 4-bromo- but-1-ene
Hughes, Gregory,Lautens, Mark,Wu, Jingxiao
, p. 835 - 837 (2007/10/03)
We report a convenient two step strategy for the attachment of but-3- enyl groups to nucleophiles. Dichloride 3 is used to introduce the 3- chlorobut-2-enyl group which is converted to the desired terminal olefin with excellent regioselectivity by a Pd ca
