118517-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118517-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,5,1 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118517-20:
(8*1)+(7*1)+(6*8)+(5*5)+(4*1)+(3*7)+(2*2)+(1*0)=117
117 % 10 = 7
So 118517-20-7 is a valid CAS Registry Number.

Aziridination of alkenes with N-substituted hydrazines mediated by iodobenzene diacetate
Li, Jiayin,Liang, Jiang-Lin,Chan, Philip Wai Hong,Che, Chi-Ming
, p. 2685 - 2688 (2004)
Aziridination of a variety of alkenes with N-substituted hydrazines mediated by iodobenzene diacetate under mild conditions (K2CO 3, CH2Cl2) and ambient temperature were achieved in good to excellent yields (up to 99%), and conversions. The practicality and simplicity of this C-N bond formation protocol was exemplified by its application to the aziridination of cholesteryl acetate in a stereoselective manner.
