1383843-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1383843-81-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,8,4 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1383843-81:
(9*1)+(8*3)+(7*8)+(6*3)+(5*8)+(4*4)+(3*3)+(2*8)+(1*1)=189
189 % 10 = 9
So 1383843-81-9 is a valid CAS Registry Number.

Rh/chiral sulfinylphosphine catalyzed asymmetric 1,4-addition of arylboronic acids to chalcones
Chen, Guihua,Xing, Junwei,Cao, Peng,Liao, Jian
, p. 5908 - 5911 (2012)
A general method to obtain enantioenriched 1,3,3-triarylpropan-1-ones bearing a diarylmethine stereocenter was developed using Rh/chiral sulfinylphosphine catalyzed 1,4-addition of arylboronic acids to chalcones. The catalysis progressed smoothly in the p
