Check Digit Verification of cas no

The CAS Registry Mumber 1421788-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,7,8 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1421788-73:
(9*1)+(8*4)+(7*2)+(6*1)+(5*7)+(4*8)+(3*8)+(2*7)+(1*3)=169
169 % 10 = 9
So 1421788-73-9 is a valid CAS Registry Number.

Sulfenate substitution as a complement and alternative to sulfoxidation in the diastereoselective preparation of chiral β-substituted β-amino sulfoxides

S?derman, Stefan C.,Schwan, Adrian L.

, p. 1638 - 1649 (2013/03/28)

Building from a previous communication, the reaction of sulfenate anions with chiral N-Boc-protected β-substituted β-amino iodides was evaluated as a conceptually different synthetic approach to chiral β-substituted β-amino sulfoxides. Using arenesulfenat
