Check Digit Verification of cas no
The CAS Registry Mumber 211449-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,4,4 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 211449-19:
(8*2)+(7*1)+(6*1)+(5*4)+(4*4)+(3*9)+(2*1)+(1*9)=103
103 % 10 = 3
So 211449-19-3 is a valid CAS Registry Number.

, p. 7947 - 7954 (1998)
4-(C(n-1)F(2n-1)-Substituted quinolines (n = 2-4) are obtained by the reaction of 2-(C(n)F(2n+1))-substituted anilines 1 with lithium enolate of acetaldehyde. A similar treatment of 1 with lithium enolates of methyl ketones, the treatment of 1 with lithiu
