117993-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117993-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,9 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117993-86:
(8*1)+(7*1)+(6*7)+(5*9)+(4*9)+(3*3)+(2*8)+(1*6)=169
169 % 10 = 9
So 117993-86-9 is a valid CAS Registry Number.

THE CARBENE COMPLEX ROUTE TO DONOR-ACCEPTOR-SUBSTITUTED CYCLOPROPANES
Wienand, Anette,Reissig, Hans-Ulrich
, p. 2315 - 2318 (2007/10/02)
A variety of donor-acceptor-substituted cyclopropanes can be synthesized starting from electron deficient olefins in preparatively usefull yields employing Fischer carbene complexes as donor-carbene source.
