Check Digit Verification of cas no

The CAS Registry Mumber 21890-35-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,9 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21890-35:
(7*2)+(6*1)+(5*8)+(4*9)+(3*0)+(2*3)+(1*5)=107
107 % 10 = 7
So 21890-35-7 is a valid CAS Registry Number.

Efficient procedures for 1-bromo-1,3-butadiene and 2-bromo-1,3-butadiene

Keegstra,Verkruijsse,Andringa,Brandsma

, p. 721 - 726 (2007/10/02)

Mixtures of Z- and E-1-bromo-1,3-butadiene in which the E- or Z- isomer predominates have been obtained in good yields by treating a mixture of Z- and E-1,4-dibromo-2-butene (90% Z-isomer) or pure E-1,4-dibromo-2-butene, respectively, with powdered potassium hydroxide in high-boiling petroleum. 2-Bromo-1,3-butadiene was obtained in high yields by stirring a mixture of vinylacetylene, concentrated aqueous hydrogen bromide and copper(I) bromide.
