123363-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123363-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,6 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123363-72:
(8*1)+(7*2)+(6*3)+(5*3)+(4*6)+(3*3)+(2*7)+(1*2)=104
104 % 10 = 4
So 123363-72-4 is a valid CAS Registry Number.

Synthesis of C19-C27 Fragment of Ansa Chain Part of Rifamycin S
Katsuki, Tsutomu,Hanamoto, Takeshi,Yamaguchi, Masaru
, p. 117 - 118 (2007/10/02)
The C19-C27 fragment of the ansa chain part of rifamycin S was stereoselectively sythesized from (4Z)-1,2-epoxy-3-methyl-4-hexene by reiterative use of stereoselective epoxidatation of cis-homoallylic alcohol and regioselective opening of the resulting ep
