79449-78-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79449-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,4 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79449-78:
(7*7)+(6*9)+(5*4)+(4*4)+(3*9)+(2*7)+(1*8)=188
188 % 10 = 8
So 79449-78-8 is a valid CAS Registry Number.

ASYMMETRIC CLEAVAGE OF CHIRAL ACETALS BY R2CuLi,BF3 REAGENTS
Ghribi, A.,Alexakis, A.,Normant, J.F.
, p. 3083 - 3086 (1984)
The title reagents cleave diastereoselectively the acetals derived from various aldehydes and chiral 2-3 butane diol (or higher homologs).This reaction affords an asymetric synthesis of secondary alcohols from an aldehyde and a trivial organolithium reage
