1184662-59-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1184662-59-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,4,6,6 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1184662-59:
(9*1)+(8*1)+(7*8)+(6*4)+(5*6)+(4*6)+(3*2)+(2*5)+(1*9)=176
176 % 10 = 6
So 1184662-59-6 is a valid CAS Registry Number.

Heterocyclic analogs of combretastatin A-4
Vasilevsky,Davydova,Tolstikov
, p. 1257 - 1261 (2008)
A novel route is proposed for the synthesis of heterocyclic analogs of the naturally occurring combretastatin A-4 based on the reaction of α-acetylenic ketones with polyfunctional nucleophiles (hydroxylamine, hydrazine, guanidine). Previously unknown combretastatin A-4 analogs with azole and azine bridges were obtained.
