917113-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917113-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,1,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917113-20:
(8*9)+(7*1)+(6*7)+(5*1)+(4*1)+(3*3)+(2*2)+(1*0)=143
143 % 10 = 3
So 917113-20-3 is a valid CAS Registry Number.

Total synthesis of the diazobenzofluorene antibiotic (-)-kinamycin C 1
Lei, Xiaoguang,Porco Jr., John A.
, p. 14790 - 14791 (2008/02/04)
The enantioselective total synthesis of the diazobenzofluorene antibiotic (-)-kinamycin C is reported. The approach involves tartrate-mediated, asymmetric nucleophilic epoxidation of a functionalized quinone monoketal to construct the highly substituted D
