Check Digit Verification of cas no
The CAS Registry Mumber 256642-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,6,4 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 256642-28:
(8*2)+(7*5)+(6*6)+(5*6)+(4*4)+(3*2)+(2*2)+(1*8)=151
151 % 10 = 1
So 256642-28-1 is a valid CAS Registry Number.

Nicosulfuron: Alcoholysis, chemical hydrolysis, and degradation on various minerals
Sabadie, Jean
, p. 526 - 531 (2002)
Alcoholysis (methanol or ethanol) and hydrolysis (pH ranging from 4 to 11) of the herbicide nicosulfuron at 30 °C principally involves the breakdown of the urea part of the molecule. A high yield of the corresponding carbarnate was obtained along with aminopyrimidine during alcoholysis. Hydrolysis led to both aminopyrimidine and pyridylsulfonamide. The latter compound may be easily cyclized (pH ≥ 7). First-order kinetics describe the rates of alcoholysis and hydrolysis well. The rate constants (0.44 days-1 for methanolysis) decreased from 0.50 to 0.002 days-1 as pH increased from 4 to 8, then remained stable under alkaline conditions. In acidic or neutral solution, the hydrolysis path appeared prevalent (≥70%), whereas in an alkaline medium it decreased when pH increased. The chemical degradation of nicosulfuron on various dry minerals (calcium bentonite, kaolinite, silica gel, H+ bentonite, montmorillonite K10, and alumina) was investigated at 30 °C. The best conditions for the degradation are obtained on acidic minerals after herbicide deposition using the liquid method. Under these conditions an acceptable correlation with pseudo-first-order kinetics was observed, and the major degradation path is similar to that proposed for chemical hydrolysis. Conversely, alumina seemed to favor other unknown degradation processes. The hydrolysis paths of nicosulfuron and rimsulfuron appeared to be different.
