688753-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 688753-70-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,7,5 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 688753-70:
(8*6)+(7*8)+(6*8)+(5*7)+(4*5)+(3*3)+(2*7)+(1*0)=230
230 % 10 = 0
So 688753-70-0 is a valid CAS Registry Number.

Stereoselective synthesis of anamarine
Díaz-Oltra, Santiago,Murga, Juan,Falomir, Eva,Carda, Miguel,Marco, J. Alberto
, p. 2979 - 2985 (2007/10/03)
A stereoselective synthesis of the naturally occurring, α,β-unsaturated lactone anamarine is described. The key step was a highly stereoselective aldol reaction of a protected erythrulose derivative with a chiral aldehyde. Another relevant step was an asy
