Check Digit Verification of cas no
The CAS Registry Mumber 1689-67-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1689-67:
(6*1)+(5*6)+(4*8)+(3*9)+(2*6)+(1*7)=114
114 % 10 = 4
So 1689-67-4 is a valid CAS Registry Number.

Photochemistry of Cis-Fused Bicyclo-2,4-dienes. Ground State Conformational Control
Dauben, William G.,Kellogg, Michael S.
, p. 4456 - 4463 (2007/10/02)
The photochemistry of a series of simple cis-fused bicyclo-2,4-dienes (n = 3,4,5) which possess flexible conformations in the ground state has been studied.The bicyclonona-2,4-diene system gave rise to cyclic trienes (ring-opened products) and cyclobutenes (ring-closed products) depending upon the wavelength of the excitation light and upon the temperature of the reaction.The bicyclodeca-2,4-diene yielded materials which are viewed as secondary photoproducts; the expected initial photoproducts could not be detected.The bicycloundeca-8,10-diene yielded both a triene and cyclobutene as primary photoproducts.No wavelength dependency was observed.The results indicate ground state conformational control of the photoreactions.
