Check Digit Verification of cas no

The CAS Registry Mumber 161875-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,7 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161875-84:
(8*1)+(7*6)+(6*1)+(5*8)+(4*7)+(3*5)+(2*8)+(1*4)=159
159 % 10 = 9

1,3-DIPOLAR CYCLOADDITION CHEMISTRY OF 2,3-BIS(PHENYLSULFONYL)-1,3-DIENE WITH DIAZOALKANES

Padwa, Albert,Meske, Michael,Rodriguez, Augusto

, p. 191 - 204 (2007/10/02)

2,3-Bis(phenylsulfonyl)-1,3-butadiene was found to react smoothly with diazomethane and diazopropane to give a mixture of 1:1- and 2:1-cycloadducts.Heating the 1:1-cycloadduct at 110 deg C resulted in loss of nitrogen and formation of mainly phenylsulfony
