Check Digit Verification of cas no
The CAS Registry Mumber 21623-88-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,2 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21623-88:
(7*2)+(6*1)+(5*6)+(4*2)+(3*3)+(2*8)+(1*8)=91
91 % 10 = 1
So 21623-88-1 is a valid CAS Registry Number.

Laser-Powered Decomposition of Spiroalkanes (n = 2-5)
Fajgar, Radek,Pola, Josef
, p. 7709 - 7717 (2007/10/02)
The laser heating of spiroalkanes (n=2-5) and of their 1,1,2,2-tetradeuterated isotopomers reveals dissimilar modes of their thermal decomposition.Spiropentane decomposes into ethene and propadiene via two competing routes: the direct cleavage and the more important cleavage via intermediary methylenecyclobutane.Spirohexane decomposes through two important concurrent pathways which are the expulsions of ethene from the three-membered ring and a more feasible expulsion of ethene from the four-membered ring.Spiroheptane and spirooctane decompose by a radical-chain mechanism and afford complex mixtures of products; upon addition of propene both compounds rearrange into two cycloalkanes wherein the larger ring of the spiroalkane is preserved and substituted with ethylidene and a vinyl group.
