Check Digit Verification of cas no
The CAS Registry Mumber 18906-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,0 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18906-12:
(7*1)+(6*8)+(5*9)+(4*0)+(3*6)+(2*1)+(1*2)=122
122 % 10 = 2
So 18906-12-2 is a valid CAS Registry Number.

A facile procedure for the generation of dichlorocarbene from the reaction of carbon tetrachloride and magnesium using ultrasonic irradiation
Lin, Haixia,Yang, Mingfa,Huang, Peigang,Cao, Weiguo
, p. 608 - 613 (2003)
An improved method for the generation of dichlorocarbene was developed that utilizes ultrasound in the reaction of carbon tetrachloride with magnesium. High yields of gem-dichlorocyclopropane derivatives can be obtained in the presence of olefins by this method.

REACTIONS OF DICHLOROCARBENE AND OF THE SIMMONS-SMITH REAGENT WITH THE DIMER AND TRIMER OF CYCLOPENTADIENE AND THE DIMER OF SPIROHEPTA-4,6-DIENE
Molchanov, A. P.,Kostikov, R. R.,Chernyshev, V. A.
, p. 1444 - 1449 (2007/10/02)
Dichlorocarbene reacts with the exo dimer of cyclopentadiene (exo-tricyclo2,6>deca-3,8-diene) and the trimer of cyclopentadiene (exo-endo-pentacyclo2,7.09,13>pentadeca-4,10-diene) at the cyclopentene double bond.The Simmons-Smith reagent, prepared from methylene iodide in presence of a zinc-silver couple, reacts with the same hydrocarbons and also with the dimer of spirohepta-4,6-diene 2,6>deca-3,8-diene)-10-spirocyclopropane> nonselectively at both double bonds, whereas it adds to the trimer of cyclopentadiene only at the norbornene double bond.
