67642-35-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67642-35-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,4 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67642-35:
(7*6)+(6*7)+(5*6)+(4*4)+(3*2)+(2*3)+(1*5)=147
147 % 10 = 7
So 67642-35-7 is a valid CAS Registry Number.

SYNTHESIS OF PHEROMONES, IV. CHEMISTRY OF THE WITTIG REACTION, I. EFFECTS OF REACTION CONDITIONS ON THE STEREOSELECTIVITY AND YIELD OF THE WITTIG REACTION

Vinczer, Peter,Juvancz, Zoltan,Novak, Lajos,Szantay, Csaba

, p. 797 - 820 (2007/10/02)

The reactions of nonstabilized triphenylphosphorus ylides with aldehydes have been studied in detail.The stereochemistry and yields of the alkene products are highly dependent upon base used for the generation of the ylide, the solvent and reaction temperature.The synthesis of sex pheromone components by Wittig reaction are also described.
