Check Digit Verification of cas no

The CAS Registry Mumber 219907-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,0 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 219907-83:
(8*2)+(7*1)+(6*9)+(5*9)+(4*0)+(3*7)+(2*8)+(1*3)=162
162 % 10 = 2
So 219907-83-2 is a valid CAS Registry Number.

Generation of near-enantiopure α-alkyl α-formyl α-hydroxy ketones/esters and their interception with ethoxycarbonylmethylenetriphenylphosphorane

Bhatia, Gurpreet S.,Lowe, Richard F.,Stoodley, Richard J.

, p. 9245 - 9248 (1998)

Two protocols for the generation of the (R)-enantiomers of α-alkyl α- formyl α-hydoxy ketones/esters in states of high enantiomeric purity are developed; the formyl functions of such compounds undergo Wittig condensations with ethoxycarbonylmethylenetriphenylphosphorane in dimethyl sulfoxide to afford the corresponding alkenes with high (E)- stereoselectivities and with e.e.s of 91-99%.
