157840-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157840-85-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,8,4 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157840-85:
(8*1)+(7*5)+(6*7)+(5*8)+(4*4)+(3*0)+(2*8)+(1*5)=162
162 % 10 = 2
So 157840-85-2 is a valid CAS Registry Number.

Enantioselective Preparation of a C3 Symmetrical Triol
Luetjens, Henning,Knochel, Paul
, p. 1161 - 1162 (2007/10/02)
The new C3 symmetrical triol 1 has been prepared in optically pure form ( > 98percent ee) using a catalytic enantioselective ethylation of a functionalized unsaturated aldehyde in an iterative way and a diastereoselective hydroboration.
