Check Digit Verification of cas no
The CAS Registry Mumber 73825-54-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,2 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 73825-54:
(7*7)+(6*3)+(5*8)+(4*2)+(3*5)+(2*5)+(1*4)=144
144 % 10 = 4
So 73825-54-4 is a valid CAS Registry Number.

Cross coupling of 3-bromopyridine and sulfonamides (R1NHSO2R2·R1 = H, Me, alkyl; R2 = alkyl and aryl) catalyzed by CuI/1,3-di(pyridin-2-yl)propane-1,3-dione

experimental part, p. 360 - 362 (2010/03/24)
N-(3-Pyridinyl)-substituted secondary and tertiary sulfonamides have been synthesized in good to excellent yields by the reaction of 3-bromopyridine with primary and secondary alkyl and aryl sulfonamides (MeSO2NH2, MeSO2NHMe, TolSO2NH2, TolSO2NHMe, 1,3-propanesultam, and 1,4-butanesultam), catalyzed by CuI (20 mol %) and 1,3-di(pyridin-2-yl)propane-1,3-dione (20 mol %) with K2CO3 (200 mol %) in DMF (0.17 M for ArBr) at 110-120 °C over 36-40 h. 2-Bromopyridine, 4-bromopyridine, and a wide variety of substituted phenyl bromides can also be successfully coupled with sulfonamides under these reaction conditions.
