636590-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 636590-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,6,5,9 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 636590-52:
(8*6)+(7*3)+(6*6)+(5*5)+(4*9)+(3*0)+(2*5)+(1*2)=178
178 % 10 = 8
So 636590-52-8 is a valid CAS Registry Number.

Asymmetric synthesis of chiral α-keto esters via Grignard addition to oxalates
MaGee, David I.,Mallais, Tammy C.,Eic, Marijanna
, p. 3177 - 3181 (2007/10/03)
While enroute to an asymmetric synthesis of the chlorine containing metabolite (-)-cryptosporiopsin an efficient and reliable asymmetric synthesis of chiral α-keto esters was required. These compounds can be conveniently generated in 51-84% yields via Gri
