Check Digit Verification of cas no
The CAS Registry Mumber 343781-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,7,8 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 343781-57:
(8*3)+(7*4)+(6*3)+(5*7)+(4*8)+(3*1)+(2*5)+(1*7)=157
157 % 10 = 7
So 343781-57-7 is a valid CAS Registry Number.

Efficient synthesis of halohydroxypyridines by hydroxydeboronation
Voisin, Anne Sophie,Bouillon, Alexandre,Lancelot, Jean-Charles,Rault, Sylvain
, p. 1417 - 1421 (2007/10/03)
This paper describes a general method for the synthesis of halohydroxypyridines from novel halopyridinylboronic acids and esters recently described by some of us. Halopyridinylboronic acids and esters have been efficiently hydroxydeboronated under mild conditions by employing hydrogen peroxide or meta-chloroperbenzoic acid. These hydroxylations take place regioselectively without other oxidation (N-oxide formation).
