Check Digit Verification of cas no
The CAS Registry Mumber 39050-39-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,0,5 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39050-39:
(7*3)+(6*9)+(5*0)+(4*5)+(3*0)+(2*3)+(1*9)=110
110 % 10 = 0
So 39050-39-0 is a valid CAS Registry Number.

Efficient and stereoselective access to the polyol fragment C9-C16 of ansamycin antibiotics
Obringer, Michel,Barbarotto, Marie,Choppin, Sabine,Colobert, Francoise
, p. 3542 - 3545 (2009)
Image Persented Efficient synthesis of the fragment C9-C16 bearing the anti, syn stereotriad of ansamycin antibiotics is described. Key steps for controlling the configuration of the three stereogenic centers involve a stereoselective Reformatsky-type reaction followed by a diastereoselective reduction of a β-ketosulfoxide.
