Check Digit Verification of cas no
The CAS Registry Mumber 21969-32-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,6 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21969-32:
(7*2)+(6*1)+(5*9)+(4*6)+(3*9)+(2*3)+(1*2)=124
124 % 10 = 4
So 21969-32-4 is a valid CAS Registry Number.

Process for preparing 1-bromoalkylbenzene derivatives and intermediates thereof
-
, (2008/06/13)
A 1-bromoalkylbenzene derivative is prepared by reacting a phenylalkene derivative with hydrogen bromide in the presence of a non-polar solvent. The phenylalkene derivative is prepared by reacting an alkenyl halide with metal magnesium to form a Grignard reagent, and then reacting the Grignard reagent with a benzyl halide derivative. An allyl Grignard reagent is prepared by reacting continuously an allyl halide derivative with metal magnesium in an organic solvent, in which the allyl halide derivative and metal magnesium are continuously added to the reaction system and the allyl Grignard reagent formed is continuously removed from the reaction system. The processes provide the intended compounds in high yields, high selectivities and high purities.
