101342-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 101342-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,3,4 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 101342-90:
(8*1)+(7*0)+(6*1)+(5*3)+(4*4)+(3*2)+(2*9)+(1*0)=69
69 % 10 = 9
So 101342-90-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 733 - 736 (2009/09/30)
(Chemical Equation Presented) Asymmetric total syntheses of (+)-azinothricin and (+)-kettapeptin have been completed through a common new pathway that exploits a highly chemoselective coupling reaction between the fully elaborated cyclodepsipeptide 5 and the glycal activated esters 3 and 4 at the final stages of both respective syntheses.
