112563-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112563-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,6 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 112563-70:
(8*1)+(7*1)+(6*2)+(5*5)+(4*6)+(3*3)+(2*7)+(1*0)=99
99 % 10 = 9
So 112563-70-9 is a valid CAS Registry Number.

A SYNTHESIS OF A SPIROCYCLOPROPANE-1,1'-CARBAPENEM
Kim, Choung Un,Misco, Peter F.,Luh, Bing Y.
, p. 1193 - 1196 (2007/10/02)
The total synthesis of the spirocyclopropane 1,1'-carbapenem 13 has been achieved through the Wittig cyclization of the phosphorane 11.A modified Simmons-Smith reaction on the olefinic ketone 6 gave the key cyclopropane derivative 7 in good yield.
