Check Digit Verification of cas no

The CAS Registry Mumber 1069137-36-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,9,1,3 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1069137-36:
(9*1)+(8*0)+(7*6)+(6*9)+(5*1)+(4*3)+(3*7)+(2*3)+(1*6)=155
155 % 10 = 5
So 1069137-36-5 is a valid CAS Registry Number.

An efficient route to polynitrogen-fused tricycles via a nitrene-mediated N-N bond formation under microwave irradiation

Nyffenegger, Coralie,Pasquinet, Eric,Suzenet, Franck,Poullain, Didier,Jarry, Christian,Léger, Jean-Michel,Guillaumet, Gérald

, p. 9567 - 9573 (2008)

The synthesis of unprecedented fused azaheterocyclic ring systems is described. Tricycles with either a central pyrazole or a triazole ring were obtained via a nitrene-mediated reaction of nitro bis(hetaryl) derivatives in the presence of triethylphosphite. The cyclization proceeded with complete chemoselectivity for the desired N-N bond formation and was completed within minutes under microwave activation. The key nitro bicycles were synthesized using either Stille couplings or aromatic nucleophilic substitution.
