Check Digit Verification of cas no
The CAS Registry Mumber 159146-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,1,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 159146-89:
(8*1)+(7*5)+(6*9)+(5*1)+(4*4)+(3*6)+(2*8)+(1*9)=161
161 % 10 = 1
So 159146-89-1 is a valid CAS Registry Number.

Photoaddition of alkenes to conjugated α-diketones: Tandem cyclizations leading to tetrasubstituted furans
Mukherjee,Margaretha,Agosta
, p. 3388 - 3391 (2007/10/03)
Photocycloaddition of 9a-c with 2 leads cleanly to tetrasubstituted furans 12a-c, respectively, in yields of ~85%. The reactive triplet is efficiently sensitized by 2-benzoylnaphthalene and quenched by anthracene, indicating that E(T) is in the range 43-58 kcal/mol. A mechanism is proposed involving an alkyl propargyl biradical (as 10) that closes first to a vinyl carbene (as 11) and then to product. Reaction of 9c with 20 furnishes only 22, and this result rules out an alternative mechanism in which the order of steps leading to the carbene is reversed.
