54731-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54731-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,3 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 54731-55:
(7*5)+(6*4)+(5*7)+(4*3)+(3*1)+(2*5)+(1*5)=124
124 % 10 = 4
So 54731-55-4 is a valid CAS Registry Number.

ASYMMETRIC INDUCTION BY CHIRAL SILICON GROUPS
Larson, Gerald L.,Torres, Evelyn
, p. 19 - 28 (1985)
The reduction of racemic RPhMeSiCCl2CH3 systems (R=cyclohexyl, isoprpyl, t-butyl and 2-mesityl) to the diastereomeric RPhMeSiCHClCH3 with tributyltin hydride was used as a probe into the potential of the RPhMeSi group to induce asymmetry at an α position.Favorable results were obtained for R=mesityl.
