Check Digit Verification of cas no

The CAS Registry Mumber 223758-96-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,7,5 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 223758-96:
(8*2)+(7*2)+(6*3)+(5*7)+(4*5)+(3*8)+(2*9)+(1*6)=151
151 % 10 = 1
So 223758-96-1 is a valid CAS Registry Number.

Reaction of 1-iodoalkynes with allylzirconiums: Generation of alkylidene carbenoid via allylzirconation

Yamanoi, Shigeo,Matsumoto, Takashi,Suzuki, Keisuke

, p. 2793 - 2796 (1999)

Allylzirconium species, generated by hydrozirconation of allenes, react with 1-iodoalkynes in the presence of methylaluminoxane (MAO) to give the substitution products of the iodide by an allyl group. Labelling study for 2- (iodoethynyl)naphthalene suggested that the reaction involves allylzirconation of iodoalkynes to generate an alkylidene carbenoid that undergoes 1,2-rearrangement.
