99966-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99966-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,6 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99966-75:
(7*9)+(6*9)+(5*9)+(4*6)+(3*6)+(2*7)+(1*5)=223
223 % 10 = 3
So 99966-75-3 is a valid CAS Registry Number.

Cycloaddition of Two C=N Double Bonds. First Structural Evidence for Head-to-tail Photodimerization in the 2-Penylbenzoxazole Series
Paillous, Nicole,Forgues, Suzanne Fery,Jaud, Joeol,Devillers, Jean
, p. 578 - 579 (1987)
Irradiation of 2-(4-fluorophenyl)benzoxazole in a two-phase medium leads to crystals of the photoadduct; the head-to-tail structure of this dimer has been demonstrated by an X-ray study.
