The CAS Registry Mumber 146663-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,6,6 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 146663-08:
(8*1)+(7*4)+(6*6)+(5*6)+(4*6)+(3*3)+(2*0)+(1*8)=143
143 % 10 = 3
So 146663-08-3 is a valid CAS Registry Number.

Ring contraction reactions of polysilacycloalkynes

Sekigawa,Shimizu,Ando

, p. 6359 - 6366 (1993)

Photoirradiation of polysilacycloalkynes in the presence of acetone provides the acetone adducts of bicyclic silacyclopropenes. Ring contraction of polysilacycloalkynes proceeds via two different pathways; one is a process via bicyclic silacyclopropene formed by rearrangement of the silicon atom adjacent to acetylene carbons and another is a direct desilylation process.
