109801-05-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109801-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,0 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109801-05:
(8*1)+(7*0)+(6*9)+(5*8)+(4*0)+(3*1)+(2*0)+(1*5)=110
110 % 10 = 0
So 109801-05-0 is a valid CAS Registry Number.

Samarium-Promoted, Stereocontrolled Cyclopropanation Reactions
Molander, Gary A.,Etter, Jeffrey B.
, p. 3942 - 3944 (1987)
Samarium-based carbenoids have been found to be highly efficient cyclopropanation reagents for allylic alcohol substrates.Hydroxyl-directed cyclopropanations occur under very mild conditions with a high degree of selectivity.
