141859-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141859-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,5 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141859-89:
(8*1)+(7*4)+(6*1)+(5*8)+(4*5)+(3*9)+(2*8)+(1*9)=154
154 % 10 = 4
So 141859-89-4 is a valid CAS Registry Number.

Asymmetric intramolecular hydrosilylation of hydroxyketones
Burk, Mark J.,Feaster, John E.
, p. 2099 - 2102 (2007/10/02)
A procedure for the catalytic asymmetric intramolecular hydrosilylation of α- and β-hydroxyketones has been developed. A cationic rhodium (I) catalyst bearing the new chiral diphosphine (R,R)-i-Pr-DuPHOS affords the product diols in up to 93% ee.
