214901-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214901-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,9,0 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 214901-04:
(8*2)+(7*1)+(6*4)+(5*9)+(4*0)+(3*1)+(2*0)+(1*4)=99
99 % 10 = 9
So 214901-04-9 is a valid CAS Registry Number.

Platinum-catalyzed enantioselective aldol addition of ketene silyl acetals to aldehydes
Fujimura, Osamu
, p. 10032 - 10039 (1998)
The first platinum-catalyzed enantioselective aldol reactions are reported. The catalysts are generated from chiral bisphosphine platinum acyl complexes by activation with noncoordinating or weakly coordinating strong acids and can be used to catalyze the
