Check Digit Verification of cas no
The CAS Registry Mumber 4447-21-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4447-21:
(6*4)+(5*4)+(4*4)+(3*7)+(2*2)+(1*1)=86
86 % 10 = 6
So 4447-21-6 is a valid CAS Registry Number.

Synthesis of 7E,9Z-dodecadienyl acetate, the sex pheromone of Lobesia botrana Shiff
Chrelashvili, Z. G.,Mavrov, M. V.,Dolidze, A. V.,Voronkov, A. P.,Serebryakov, E. P.
, p. 734 - 736 (2007/10/02)
Two syntheses of 7E,9Z-dodecadienyl acetate from 1,3-butadiyne were carried out using either 2E,4Z-heptadienyl acetate or 1-bromo-3E,5Z-octadiene as the key intermediates.The latter underwent organocopper cross-coupling with the respective complementary Grignard reagents (prepared from the corresponding 1-tert-butoxy-ω-chlorohydrins) as alkylating agents.
