Check Digit Verification of cas no

The CAS Registry Mumber 643022-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,0,2 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 643022-62:
(8*6)+(7*4)+(6*3)+(5*0)+(4*2)+(3*2)+(2*6)+(1*2)=122
122 % 10 = 2
So 643022-62-2 is a valid CAS Registry Number.

Highly Enantioselective Synthesis of 1,2-Amino Alcohol Derivatives via Proline-Catalyzed Mannich Reaction

Pojarliev, Peter,Biller, William T.,Martin, Harry J.,List, Benjamin

, p. 1903 - 1905 (2003)

Here we report a new catalytic asymmetric synthesis of oxazolidin-2-ones 4 and Cbz-protected 1,2-amino alcohols 5. Our sequence is based on the chemistry of previously unknown 5-acyloxy-oxazolidin-2-ones, which are obtained via proline-catalyzed direct asymmetric three-component Mannich reaction and Baeyer-Villiger oxidation.
