16281-42-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16281-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,8 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16281-42:
(7*1)+(6*6)+(5*2)+(4*8)+(3*1)+(2*4)+(1*2)=98
98 % 10 = 8
So 16281-42-8 is a valid CAS Registry Number.

Asymmetric Synthesis of Mellein Methyl Ether: Use of ortho-Toluate Carbanions Generated by Chiral Bases
Regan, Andrew C.,Staunton, James
, p. 764 - 765 (1983)
An ortho-toluate carbanion generated from (2) by the chiral lithium amide base (6), (7), or (11) undergoes an enantioselective aldol-type reaction with acetaldehyde to give mellein methyl ether (3), in up to 53 percent enantiomeric excess.
