157999-16-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157999-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,9 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157999-16:
(8*1)+(7*5)+(6*7)+(5*9)+(4*9)+(3*9)+(2*1)+(1*6)=201
201 % 10 = 1
So 157999-16-1 is a valid CAS Registry Number.

Synthesis of Chiral Diether and Tetraether Phospholipids: Regiospecific Ring Opening of Epoxy Alcohol Intermediates Derived from Asymmetric Epoxidation

Thompson, David H.,Svendsen, Chris B.,Meglio, Ciro Di,Anderson, Valerie C.

, p. 2945 - 2955 (1994)

Diether and tetraether phospholipids have been synthesized using chiral epoxy alcohol starting materials (e.g. glycidol 3-nitrobenzenesulfonate esters or tert-butyldiphenylsilyl ethers).These chiral precursors provide control over the stereochemistry, sub
