Check Digit Verification of cas no
The CAS Registry Mumber 72668-36-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,6 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72668-36:
(7*7)+(6*2)+(5*6)+(4*6)+(3*8)+(2*3)+(1*6)=151
151 % 10 = 1
So 72668-36-1 is a valid CAS Registry Number.

Pheromone synthesis. Part 261: Synthesis of four pyrazines produced by females of the Korean apricot wasp, Eurytoma maslovskii
Mori, Kenji,Yang, Chang Yeol
, p. 4766 - 4769 (2017/07/17)
Four pyrazines were synthesized as sex specific volatiles of female Korean apricot wasp, Eurytoma maslovskii. They are 2,5-dimethyl-3-vinylpyrazine (1), 2,5-dimethyl-3-(2-methylpropyl)pyrazine (2), 2,5-dimethyl-3-(2-methylbutyl)pyrazine (3), and 2,5-dimethyl-3-(3-methylbutylpyrazine (4). They were synthesized in 74–85% yields by Pd- or Fe-catalyzed cross-coupling reactions between 3-chloro-2,5-dimethylpyrazine and CH2=CHBF3K or RMgBr. The present synthesis of 1 is the most reliable and scalable one to date.
