Check Digit Verification of cas no

The CAS Registry Mumber 138221-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138221-75:
(8*1)+(7*3)+(6*8)+(5*2)+(4*2)+(3*1)+(2*7)+(1*5)=117
117 % 10 = 7
So 138221-75-7 is a valid CAS Registry Number.

Boron Trifluoride-promoted Reaction of 4'-Nitrobenzenesulphenanilide with Alkynes. Formal Addition of Benzenesulphenyl Fluoride to Carbon-Carbon Triple Bonds

Benati, Luisa,Montevecchi, P. Carlo,Spagnolo, Piero

, p. 1690 - 1695 (2007/10/02)

The BF3-promoted reaction of 4'-nitrobenzenesulphenanilide with simple alkyl- and aryl-alkynes at 80 deg C in the presence of tetrabutylammonium tetrafluoroborate provides a one-pot synthetic route to β-fluorovinyl sulphides via a formal regioselective and trans-stereospecific addition of benzenesulphenyl fluoride towards carbon-carbon triple bonds.
