Check Digit Verification of cas no
The CAS Registry Mumber 189329-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,2 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189329-48:
(8*1)+(7*8)+(6*9)+(5*3)+(4*2)+(3*9)+(2*4)+(1*8)=184
184 % 10 = 4
So 189329-48-4 is a valid CAS Registry Number.

Regio- and stereoselective addition of methane- and bromomethanesulfonyl bromides to 1-Phenylthiotricyclo[4.1.0.02,7]heptane
Vasin,Kostryukov,Neverov,Razin
, p. 624 - 627 (2010)
1-Phenylthiotricyclo[4.1.0.02,7]heptane reacted with MeSO 2Br and BrCH2SO2Br directly at mixing at 20°C in CH2Cl2 along a ionic (electrophilic with respect to bromine) mechanism affording a product of an anti-stereoselective addition to the central bicyclobutane C1-C7 bond of the norpinane structure. The reaction product contains the exo-oriented sulfonyl group in the geminal position to the SPh substituent. The structure of the adduct with MeSO2Br in a single crystal was determined by XRD analysis. Pleiades Publishing, Ltd., 2010.
