α-(Diethylamino-5 phenyl-4 oxathiole-1,3 ylidene-2) thioacetophenone is a complex organic chemical compound with the molecular formula C18H20NOS2. It is characterized by a thioacetophenone core, which is a derivative of acetophenone, where one of the hydrogen atoms on the carbonyl group is replaced by a sulfur atom. The molecule features a diethylamino group attached to the alpha carbon, which is adjacent to the carbonyl group, and a 5-phenyl-4-oxathiole ring system. This ring system consists of a benzene ring fused to a thiophene ring, with an oxygen atom incorporated into the thiophene ring, creating an oxathiole. The compound is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals due to its unique structural features and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 77654-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,5 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77654-77:
(7*7)+(6*7)+(5*6)+(4*5)+(3*4)+(2*7)+(1*7)=174
174 % 10 = 4
So 77654-77-4 is a valid CAS Registry Number.
