Check Digit Verification of cas no

The CAS Registry Mumber 1133322-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,3,2 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1133322-57:
(9*1)+(8*1)+(7*3)+(6*3)+(5*3)+(4*2)+(3*2)+(2*5)+(1*7)=102
102 % 10 = 2
So 1133322-57-2 is a valid CAS Registry Number.

Polyalkoxybenzenes from plant sources 2. Synthesis of isoxazoline analogs of combretastatin from natural allyl(methylenedioxy)methoxybenzenes

Tsyganov,Yakubov,Konyushkin,Firgang,Semenov

experimental part, p. 2460 - 2465 (2009/02/05)

A series of analogs of the natural mitostatic agent combretastatin were synthesized by the reaction of nitrile oxides with natural allylbenzenes, such as myristicin, apiol, and dillapiol. The 1,3-dipolar cycloaddition reactions in allylic systems proceed regiospecifically. The reactions with trans isomers of propenylbenzenes, viz., isomyristicin, isoapiol, and isodillapiol, as dipolarophiles produce regioisomers.
