119238-15-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119238-15-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,3 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119238-15:
(8*1)+(7*1)+(6*9)+(5*2)+(4*3)+(3*8)+(2*1)+(1*5)=122
122 % 10 = 2
So 119238-15-2 is a valid CAS Registry Number.

Practical synthesis of chiral ligands for catalytic enantioselective cyanosilylation of ketones

Masumoto, Shuji,Yabu, Kazuo,Kanai, Motomu,Shibasaki, Masakatsu

, p. 2919 - 2922 (2002)

A practical and more environmentally benign synthetic route of chiral ligands that are useful for catalytic enantioselective cyanosilylation of ketones is described. A key step is the regioselective SN2 reaction to cyclic sulfate 12 with catech
