Check Digit Verification of cas no

The CAS Registry Mumber 118491-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,9 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118491-95:
(8*1)+(7*1)+(6*8)+(5*4)+(4*9)+(3*1)+(2*9)+(1*5)=145
145 % 10 = 5
So 118491-95-5 is a valid CAS Registry Number.

PHOTOCYCLOADDITION OF ETHENES TO CYANOANISOLES

Al-Jalal, Nader,Gilbert, Andrew,Heath, Peter

, p. 1449 - 1460 (2007/10/02)

The photoreactions of 2-, 3-, and 4-cyanoanisole with cis cyclo-octene, ethyl vinyl ether and acrylonitrile have been investigated.Additions of cyclo-alkene reflect control of the reaction by the methoxy group to give predominantly meta cycloadducts by 2,6-attack.In contrast these arenes and ethyl vinyl ether undergo ortho cycloaddition which in the case of the product from the 2-arene isomer, leads to a convenient high yield synthesis of the bicycloocta-2,7-diene (23).The reactions of acrylonitrile with 2- and 3-cyanoanisoles are slow and non-selective but ortho cycloadducts are formed from the 4-isomer which also undergoes novel photoaddition with the cyano group of both acrylonitrile and benzonitrile to give azacyclo-octatetraenes.
