Manufacturing Process
Hydrocortisone (25 g) and bendazac chloride (21 g) are suspended in
anhydrous dioxane (250 ml). Pyridine (6 ml) is added and the solution is kept
under stirring for 2 hours at room temperature. Pyridine hydrochloride which
separates is filtered and the clear dioxane solution is added, under strong
stirring, to a solution of sodium bicarbonate (20 g) in distilled water (2,500
ml). The colorless precipitate which is formed is filtered, washed with water
and dried on a porous plate. The substance crystallizes from ethanol. Needles.

Check Digit Verification of cas no
The CAS Registry Mumber 53716-43-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,1 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53716-43:
(7*5)+(6*3)+(5*7)+(4*1)+(3*6)+(2*4)+(1*3)=121
121 % 10 = 1
So 53716-43-1 is a valid CAS Registry Number.
