Check Digit Verification of cas no

The CAS Registry Mumber 1260104-28-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,1,0 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1260104-28:
(9*1)+(8*2)+(7*6)+(6*0)+(5*1)+(4*0)+(3*4)+(2*2)+(1*8)=96
96 % 10 = 6
So 1260104-28-6 is a valid CAS Registry Number.

Synthesis and photochemistry of 3-(o-stilbeneyl)-4-H/Me/Ph-sydnones; Intramolecular cyclization to 1,2-benzodiazepines and/or quinolines

Butkovi?, Kristina,Vuk, Dragana,Marini?, ?eljko,Peni?, Josip,?indler-Kulyk, Marija

experimental part, p. 9356 - 9362 (2011/01/12)

Stilbeneylsydnone derivatives were synthesized by a sequence of reactions in good yields. Irradiation of 3-stilbeneyl-4-methylsydnone 4 gives 1H-1,2-benzodiazepine derivative 7 as the main product along with 2-methylquinoline derivative 20. Irradiation of 3-stilbeneyl-4-phenylsydnone 5 afforded only 1H-1,2-benzodiazepine derivative 8 whereas on irradiation of 4-unsubstituted 3-stilbeneylsydnone 3 no benzodiazepine derivative was detected. An efficient novel photochemical approach to 1H-1,2-benzodiazepines has been found from the new 3-(o-stilbeneyl)-4-substituted-sydnones via intramolecular 1,7-electrocyclization reaction of the photogenerated nitrile imines.
