133218-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133218-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,1 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133218-70:
(8*1)+(7*3)+(6*3)+(5*2)+(4*1)+(3*8)+(2*7)+(1*0)=99
99 % 10 = 9
So 133218-70-9 is a valid CAS Registry Number.

Enantiospecific Synthesis of (4S,5S,6S)-4,5,6-Trihydroxycyclohex-2-enone and (+)-Conduritol C from Fluorobenzene via Microbial Oxidation
Carless, Howard A. J.,Oak, Ozer Z.
, p. 61 - 62 (2007/10/02)
Epoxidation of the chiral diene 5, produced by Pseudomonas putida oxidation of fluorobenzene, gave fluoroconduritol 9 and cyclohexenone 11; the latter was used in a short synthesis of (+)-conduritol C 1.
