Reactivity Profile
STILBENE YELLOW is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
Fire Hazard
Flash point data for STILBENE YELLOW are not available; however, STILBENE YELLOW is probably combustible.
Check Digit Verification of cas no
The CAS Registry Mumber 1325-37-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1325-37:
(6*1)+(5*3)+(4*2)+(3*5)+(2*3)+(1*7)=57
57 % 10 = 7
So 1325-37-7 is a valid CAS Registry Number.
