Check Digit Verification of cas no

The CAS Registry Mumber 851764-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,7,6 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 851764-30:
(8*8)+(7*5)+(6*1)+(5*7)+(4*6)+(3*4)+(2*3)+(1*0)=182
182 % 10 = 2
So 851764-30-2 is a valid CAS Registry Number.

Direct amino acid-catalyzed asymmetric desymmetrization of meso-compounds: Tandem aminoxylation/O-N bond heterolysis reactions

Ramachary, Dhevalapally B.,Barbas III, Carlos F.

, p. 1577 - 1580 (2005)

(Chemical Equation Presented) A practical organocatalytic process for the synthesis of optically active, highly substituted α-hydroxy-ketones was achieved through asymmetric desymmetrization (ADS) of prochiral ketones. The ADS and O-N bond reduction reaction of prochiral ketone with nitrosobenzene in the presence of a catalytic amount of chiral amine or amino acid produced the tandem ADS/O-N bond reduced products as single diastereomers with good yields and excellent enantiomeric excesses.
