524929-34-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 524929-34-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,4,9,2 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 524929-34:
(8*5)+(7*2)+(6*4)+(5*9)+(4*2)+(3*9)+(2*3)+(1*4)=168
168 % 10 = 8
So 524929-34-8 is a valid CAS Registry Number.

Diastereocontrolled synthesis of (-)-codonopsinine
Haddad, Mansour,Larchevêque, Marc
, p. 274 - 276 (2007/10/03)
An efficient process is described for the total synthesis of the alkaloid (-)-codonopsinine. The synthetic strategy is based on the diastereoselective hydrocyanation of a 2,3-dialkoxyaldehyde derived from L-threonine followed by a reductive alkylation of
