134834-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134834-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,3 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134834-39:
(8*1)+(7*3)+(6*4)+(5*8)+(4*3)+(3*4)+(2*3)+(1*9)=132
132 % 10 = 2
So 134834-39-2 is a valid CAS Registry Number.

New Polymer Bound Chiral Catalyst with Methylene Spacer for the Enantioselective Addition of Diethylzinc to Aldehydes
Soai, Kenso,Watanabe, Masami
, p. 97 - 100 (2007/10/02)
Optically active sec-alcohols in good to high e.e.'s were obtained from the enantioselective addition of diethylzinc to both aliphatic and aromatic aldehydes using a polymer attached chiral catalyst with a methylene spacer.
