126865-15-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126865-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,6 and 5 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126865-15:
(8*1)+(7*2)+(6*6)+(5*8)+(4*6)+(3*5)+(2*1)+(1*5)=144
144 % 10 = 4
So 126865-15-4 is a valid CAS Registry Number.

Heterocyclic ring-analogs of dihydropyridine calcium antagonists
Taylor,Anderson,Badger
, p. 1353 - 1356 (2007/10/02)
An improved synthesis of the 1,4-dihydropyrazine derivative, 3, is described that involves the versatile 1,4-diketointermediate, 9. This intermediate was converted to several heterocyclic ring-analogs of 1,4-dihydropyridine in addition to 3 including deri
