Check Digit Verification of cas no

The CAS Registry Mumber 1650-46-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1650-46:
(6*1)+(5*6)+(4*5)+(3*0)+(2*4)+(1*6)=70
70 % 10 = 0
So 1650-46-0 is a valid CAS Registry Number.

Sequential assembly strategy for tetrasubstituted olefin synthesis using vinyl 2-pyrimidyl sulfide as a platform

Itami, Kenichiro,Mineno, Masahiro,Muraoka, Nobuhiro,Yoshida, Jun-Ichi

, p. 11778 - 11779 (2007/10/03)

We have developed a programmable and diversity-oriented synthetic scheme for tetrasubstituted olefins through a site-selective and sequential assembly of π-components onto a C=C core of vinyl 2-pyrimidyl sulfide. Noteworthy features are that (i) all components assembled stem from readily available organic halides or their Grignard reagents, (ii) the installation at the desired position can be achieved by the addition of the components in the appropriate order, and (iii) simple alteration of addition order in the sequence results in the production of all possible regio- and stereoisomers of multisubstituted olefins.
