652987-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 652987-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,2,9,8 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 652987-50:
(8*6)+(7*5)+(6*2)+(5*9)+(4*8)+(3*7)+(2*5)+(1*0)=203
203 % 10 = 3
So 652987-50-3 is a valid CAS Registry Number.

Solid Phase Synthesis of 1,2-Disubstituted Alkenes: A Novel Alkynyldihydropyridine to Alkenylpyridine Isomerization
Chen, Chixu,Wang, Bowei,Munoz, Benito
, p. 2404 - 2406 (2007/10/03)
A series of 1,2-disubstituted pyridylalkenes have been prepared using a solid-phase resin approach. This approach takes advantage of a novel alkynyldihydropyridine to alkenylpyridine isomerization.
