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.

Tetrasubstituted Furans from Novel Photocycloaddition of Conjugated Acetylenic α-Diketones with Alkenes

Mukherjee, Ashis K.,Agosta, William C.

, p. 1821 - 1822 (2007/10/02)

Photocycloaddition of ketones 1a - c with tetramethylethylene 2 furnishes tetrasubstituted furans 3a - c in isolated yields of ca. 85percent; a suggested mechanism for formation of 3a involves cycloaddition by way of an initial biradical 5 to form
