159835-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159835-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,3 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 159835-84:
(8*1)+(7*5)+(6*9)+(5*8)+(4*3)+(3*5)+(2*8)+(1*4)=184
184 % 10 = 4
So 159835-84-4 is a valid CAS Registry Number.

Intramolecular hydrogen bond effect in meta-cycloaddition of arene to olefin
Zhang,Guo
, p. 3157 - 3165 (1994)
The intramolecular meta-photocycloaddition of bichromophores 1a and 1b is examined and the observed stereochemistry of cycloaddition is rationalized in terms of hydrogen bond effect introduced by the 3-hydroxy group in the 5-phenylpent-1-ene skeleton.
