358973-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 358973-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,8,9,7 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 358973-99:
(8*3)+(7*5)+(6*8)+(5*9)+(4*7)+(3*3)+(2*9)+(1*9)=216
216 % 10 = 6
So 358973-99-6 is a valid CAS Registry Number.

Photocyclization of a conjugated triaryl 'Y-enyne'
Kaafarani, Bilal R.,Neckers, Douglas C.
, p. 4099 - 4102 (2007/10/03)
Upon irradiation at 350 nm, in the presence/absence of oxygen, 'Y-enyne' 1 undergoes electrocyclic ring closure to photoproduct 4. A mechanism involving an allene intermediate is proposed. In nonpolar solvents a [1,5] H shift affords the photoproduct, whi
