335197-26-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 335197-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,5,1,9 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 335197-26:
(8*3)+(7*3)+(6*5)+(5*1)+(4*9)+(3*7)+(2*2)+(1*6)=147
147 % 10 = 7
So 335197-26-7 is a valid CAS Registry Number.

Total synthesis of the anticancer natural product OSW-1

Yu, Wensheng,Jin, Zhendong

, p. 6576 - 6583 (2007/10/03)

The highly potent anticancer natural saponin OSW-1 has been successfully synthesized from commercially available 5-androsten-3β-ol-17-one 79 in 10 operations with 28% overall yield. The key steps in the total synthesis included a highly regio- and stereoselective selenium dioxide-mediated allylic oxidation of 80 and a highly stereoselective 1,4-addition of α-alkoxy vinyl cuprates 68 to steroid 17(20)-en-16-one 12E to introduce the steroid side chain. This total synthesis demonstrated once again the versatile synthetic applications of α-halo vinyl ether chemistry developed in our laboratories.
