Check Digit Verification of cas no

The CAS Registry Mumber 25804-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,0 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25804-58:
(7*2)+(6*5)+(5*8)+(4*0)+(3*4)+(2*5)+(1*8)=114
114 % 10 = 4
So 25804-58-4 is a valid CAS Registry Number.

Irradiation of neat liquid ethyl cinnamate at room temperature and of ethyl cinnamate glasses at -80 and -196 deg C produces cyclodimers in high yield.Six of the possible eleven isomers have been identified in the products.Their contributions to the overa

EXCITED STATE MULTIPLICITY INVOLVED IN PHOTOCYCLOADDITION OF POLYMETHYLENE DICINNAMATES AS STUDIED BY QUENCHING EXPERIMENTS

Kuzuya, Masayuki,Yokota, Naohisa,Tanaka, Mitsushi,Okuda, Takachiyo

, p. 1467 - 1470 (1985)

The excited state multiplicity involved in photocycloaddition of polymethylene dicinnamates was studied by quenching experiments using ferrocene, and the ratio of such multiplicities deduced from the Stern-Volmer plots based on a generalized Stern-Volmer expression was shown to vary depending upon the substituent and the methylene chain.
