135909-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135909-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,0 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135909-82:
(8*1)+(7*3)+(6*5)+(5*9)+(4*0)+(3*9)+(2*8)+(1*2)=149
149 % 10 = 9
So 135909-82-9 is a valid CAS Registry Number.

A General Route to Enantiomerically Pure Sulfoxides from a Chiral Sulfite
Rebiere, F.,Samuel, O.,Ricard, L.,Kagan, H.B.
, p. 5991 - 5999 (1991)
Enantiomerically pure cyclic chiral sulfite (S)-7 (trans stereochemistry) has been easily obtained in two steps from (S)-ethyl lactate.This compound was found to react cleanly with many organometallics to give crystalline sulfinates with high regioselecti
