Check Digit Verification of cas no
The CAS Registry Mumber 61561-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,5,6 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 61561-70:
(7*6)+(6*1)+(5*5)+(4*6)+(3*1)+(2*7)+(1*0)=114
114 % 10 = 4
So 61561-70-4 is a valid CAS Registry Number.

, p. 2226 - 2228 (2007/10/02)
N-Acetyl- and N-formyl-1,2-dihydroquinolone were conviniently prepared by reductive acylation of quinoline without isolating the labile 1,2-dihydroquinoline.This method was also applied to isoquinoline to prepare N-acetyl-1,2-dihydroisoquinoline.
