158673-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158673-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,7 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 158673-97:
(8*1)+(7*5)+(6*8)+(5*6)+(4*7)+(3*3)+(2*9)+(1*7)=183
183 % 10 = 3
So 158673-97-3 is a valid CAS Registry Number.

An enantioselective total synthesis of (+)-altholactone from diethyl L-tartrate
Somfai, Peter
, p. 11315 - 11320 (2007/10/02)
An enantioselective total synthesis of the cis-fused tetrahydrofurano-2-pyrone(+)-altholactone (1) from diethyl L-tartrate via the L-threitol derivative 2 is described. The remaining two stereogenic centers of 1 are introduced by a highly stereoselective
