441284-62-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 441284-62-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,2,8 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 441284-62:
(8*4)+(7*4)+(6*1)+(5*2)+(4*8)+(3*4)+(2*6)+(1*2)=134
134 % 10 = 4
So 441284-62-4 is a valid CAS Registry Number.

Synthesis of (1R,2S)-1-(3′-chloro-4′-methoxyphenyl)-1,2- propanediol (trametol) and (1R,2S)-1-(3′,5′-dichloro-4′- methoxyphenyl)-1,2-propanediol, chlorinated fungal metabolites in the natural environment

Kousaka, Takeshi,Mori, Kenji

, p. 697 - 701 (2002)

(1R,2S)-1-(3′-Chloro-4′-methoxyphenyl)-1,2-propanediol (Trametol, 3), a metabolite of the fungus Trametes sp. IVP-F640 and Bjerkandera sp. BOS55, was synthesized by employing Sharpless asymmetric dihydroxylation as the key step. Similarly, the (1R,2S)-isomer of 1-(3′,5′-dichloro- 4′-methoxyphenyl)-1,2-propanediol (4), another metabolite of Bjerkandera sp. BOS55, was synthesized by asymmetric dihydroxylation.
