1420779-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1420779-16-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,7,7 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1420779-16:
(9*1)+(8*4)+(7*2)+(6*0)+(5*7)+(4*7)+(3*9)+(2*1)+(1*6)=153
153 % 10 = 3
So 1420779-16-3 is a valid CAS Registry Number.

Sulfur-substituted dihydropyridones prepared by aza-Diels-Alder reactions were converted to the cis-2,6-disubstituted derivatives, which could then proceed through ring-closing metathesis (RCM) and cross metathesis (CM) reactions to give many quinolizidin
