Check Digit Verification of cas no

The CAS Registry Mumber 1151854-85-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,1,8,5 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1151854-85:
(9*1)+(8*1)+(7*5)+(6*1)+(5*8)+(4*5)+(3*4)+(2*8)+(1*5)=151
151 % 10 = 1
So 1151854-85-1 is a valid CAS Registry Number.

Lewis acid-promoted electron transfer deoxygenation of epoxides, sulfoxides, and amine N-oxides: the role of low-valent niobium complexes from NbCl5 and Zn

Oh, Kyungsoo,Knabe, William Eric

, p. 2966 - 2974 (2009)

A mild and operationally simple deoxygenation of epoxides, sulfoxides, and amine N-oxides is described using a sub-stoichiometric amount of low-valent niobium complexes generated in situ from commercially available NbCl5 and zinc dust. The deoxygenation proceeds by a reductive cleavage of polarized O-C/O-N/O-S bonds through a single electron transfer from zinc metal to the niobium-substrate complex due to the high oxophilic nature of the niobium species. The presence of adjacent radical-stabilizing groups is beneficial to epoxide substrates; however the similar prerequisite does not apply to sulfoxides and amine N-oxides, where a broad range of substrates are efficiently deoxygenated in excellent yields.
