Check Digit Verification of cas no

The CAS Registry Mumber 163180-51-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,1,8 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163180-51:
(8*1)+(7*6)+(6*3)+(5*1)+(4*8)+(3*0)+(2*5)+(1*1)=116
116 % 10 = 6
So 163180-51-6 is a valid CAS Registry Number.

Control of the ambident reactivity of the nitrite ion

Dong, Hai,Rahm, Martin,Thota, Niranjan,Deng, Lingquan,Brinck, Tore,Ramstroem, Olof

, p. 648 - 653 (2013/02/26)

In previous studies, it was reported that a neighbouring equatorial ester group is essential for a good yield of nitrite-mediated triflate inversion, whereas with neighbouring benzyl ether groups or axial ester groups, mixtures are generally produced. In

Regioselective benzoylation of 6-O-protected and 4,6-O-diprotected hexopyranosides as promoted by chiral and achiral ditertiary 1,2-diamines

Hu, Guixian,Vasella, Andrea

, p. 4369 - 4391 (2007/10/03)

Monobenzoylation of triols (6-O-silylated glycopyranosides) or diols (4,6-O-benzylidenated glycopyranosides) with benzoyl chloride and triethylamine at - 60° to 23° is promoted by catalytic amounts of ditertiary 1,2-diamines. The regioselectivity depends
