1420779-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1420779-23-2 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, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1420779-23:
(9*1)+(8*4)+(7*2)+(6*0)+(5*7)+(4*7)+(3*9)+(2*2)+(1*3)=152
152 % 10 = 2
So 1420779-23-2 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
