7332-27-6 Usage
Originator
Amcinafide,Onbio Inc.
Uses
Anti-inflammatory.
Manufacturing Process
1 ml 72% perchloric acid was added to a suspension of 4 g triamcinolone in
100 ml of fresh distilled acetophenone and the mixture was stirred at a room
temperature before all triamcinolone solved (for about 2 hours). The solution
was neutralized with help of 8 ml of 1.1 N sodium hydroxide and sufficient
quantity of sodium bicarbonate. Then chloroform and water were added.
Organic layer was separated and concentrated in vacuum. The residue was
recrystallized from acetone-hexane and thoroughly washed from
acetophenone with hexane. Triamcinolone acetophenide (amicinafide) was
prepared. It had MP: 281°-283°C (decomp.);αD
23 = +23°. (c = 0.98 in
CHCl3).
Check Digit Verification of cas no
The CAS Registry Mumber 7332-27-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7332-27:
(6*7)+(5*3)+(4*3)+(3*2)+(2*2)+(1*7)=86
86 % 10 = 6
So 7332-27-6 is a valid CAS Registry Number.
