"6,7-dimethyl-3-phenyl-4H-furo[3,2-b][1,4]thiazine-2-carbonitrile 1,1-dioxide" is a complex organic compound with a unique chemical structure. It is characterized by the presence of a furo[3,2-b][1,4]thiazine ring system, which is a fusion of a furan and a thiazine ring. The molecule features two methyl groups at the 6 and 7 positions, a phenyl group at the 3 position, and a carbonitrile group at the 2 position. The 1,1-dioxide functional group indicates the presence of two oxygen atoms bonded to the same carbon atom, which is a characteristic of sulfonamide derivatives. 6,7-dimethyl-3-phenyl-4H-furo[3,2-b][1,4]thiazine-2-carbonitrile 1,1-dioxide is likely to be of interest in the field of organic chemistry, potentially for its pharmaceutical or chemical properties, although specific applications or uses are not detailed in the provided information.

Check Digit Verification of cas no

The CAS Registry Mumber 4938-90-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4938-90:
(6*4)+(5*9)+(4*3)+(3*8)+(2*9)+(1*0)=123
123 % 10 = 3
So 4938-90-3 is a valid CAS Registry Number.
