Check Digit Verification of cas no

The CAS Registry Mumber 117972-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,7 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117972-66:
(8*1)+(7*1)+(6*7)+(5*9)+(4*7)+(3*2)+(2*6)+(1*6)=154
154 % 10 = 4
So 117972-66-4 is a valid CAS Registry Number.

HOMO-DIELS-ALDER AND ENE REACTIONS OF PHOSPHAALKYNES

Annen, Ulrich,Regitz, Manfred

, p. 1681 - 1684 (1988)

Cycloalka-1,3-dienes 1 and 6 react with phosphaalkynes 2 to form the bicyclic systems 3 and 7 containing λ3?2-phosphorus atoms.Products 3 and 7 react with a further equivalent of 2 to furnish the tetracycles 4 and 8 by way of a previously unknown homo-Diels-Alder reaction.The ene reaction 9 + 2 - 10 defines the limits of the cycloaddition process.
