Check Digit Verification of cas no

The CAS Registry Mumber 612-09-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 612-09:
(5*6)+(4*1)+(3*2)+(2*0)+(1*9)=49
49 % 10 = 9
So 612-09-9 is a valid CAS Registry Number.

Effect of micellar medium on photoannelation vs energy transfer in the system excited cyclohex-2-en-1-one-cyclopentadiene

Kumar, M. Suresh,Rao, Jampani Madhusudana

, p. 5383 - 5388 (2007/10/02)

The relative ratio of enone-CPD adducts and C15H18 formed in the photochemical reaction between cyclohex-2-en-1-one and its 4,4 dimethyl derivative and CPD in different media suggest that an exciplex is responsible for 2+2 photoannelation and energy transfer and a transoid or twisted enone for photo Diels-Alder reaction.
