99903-35-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99903-35-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,0 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99903-35:
(7*9)+(6*9)+(5*9)+(4*0)+(3*3)+(2*3)+(1*5)=182
182 % 10 = 2
So 99903-35-2 is a valid CAS Registry Number.

PREPARATION OF OPTICALLY ACTIVE ALLYLSILANES BY CATALYTIC ASYMMETRIC HYDROSILYLATION OF 1-ARYLBUTADIENES
Hayashi, Tamio,Kabeta, Keiji
, p. 3023 - 3026 (1985)
Asymmetric hydrosilylation of 1-arylbutadienes with trichlorosilane in the presence of a chiral ferrocenylphosphine-palladium catalyst gave optically active allylsilanes, (Z)-1-aryl-1-silyl-2-butenes and their regioisomers.
