444992-83-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 444992-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,9,9 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 444992-83:
(8*4)+(7*4)+(6*4)+(5*9)+(4*9)+(3*2)+(2*8)+(1*3)=190
190 % 10 = 0
So 444992-83-0 is a valid CAS Registry Number.

Synthesis of combretastatins A-1 and B-1

Odlo, Kristin,Klaveness, Jo,Rongved, P?l,Hansen, Trond Vidar

, p. 1101 - 1103 (2006)

Combretastatins A-1 and B-1 have been synthesized by coupling MOM-protected p-iodomethoxycatechol with 3,4,5-trimethoxyphenylacetylene in a Sonogashira reaction.

Direct biooxidation of arenes to corresponding catechols with E. coli JM109 (pDTG602). Application to synthesis of combretastatins A-1 and B-1

Bui, Vu P,Hudlicky, Tomas,Hansen, Trond V,Stenstrom, Yngve

, p. 2839 - 2841 (2007/10/03)
