Check Digit Verification of cas no

The CAS Registry Mumber 678149-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,4 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 678149-14:
(8*6)+(7*7)+(6*8)+(5*1)+(4*4)+(3*9)+(2*1)+(1*4)=199
199 % 10 = 9
So 678149-14-9 is a valid CAS Registry Number.

A Flexible Approach for the Asymmetric Synthesis of N-Protected (R) -5-Alkyl Tetramates and (R)-5-Alkyl Tetramic Acid Derivatives

Huang, Pei-Qiang,Deng, Jun

, p. 247 - 250 (2004)

A flexible two-step asymmetric approach to N-protected (R)-5-alkyl tetramates and (R)-5-alkyl tetramic acid derivatives is described. The method is based on the diastereoselective alkylation of (R)-phenylglycinol derived tetramates 7 and 8, which are the
