3937-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3937-95-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,3 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3937-95:
(6*3)+(5*9)+(4*3)+(3*7)+(2*9)+(1*5)=119
119 % 10 = 9
So 3937-95-9 is a valid CAS Registry Number.

Syntheses of Some Alkyl, Cycloalkyl and Aryl 3-Aminophenyl Sulfones
Courtin, Alfred
, p. 1849 - 1853 (2007/10/02)
Syntheses of alkyl (1a-1i, 1m), cycloalkyl (1j, 1k) and aryl (1l) 3-aminophenyl sulfones were achieved by ethanolic Bechamp-reduction of the appropriate 3-nitrophenyl sulfones (3a-3m).The alkyl (3a-3i) and cycloalkyl (3j, 3k) 3-nitrophenyl sulfones were p
