Check Digit Verification of cas no

The CAS Registry Mumber 98381-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,8 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98381-19:
(7*9)+(6*8)+(5*3)+(4*8)+(3*1)+(2*1)+(1*9)=172
172 % 10 = 2
So 98381-19-2 is a valid CAS Registry Number.

THE TRAPPING OF SULFENIC ACIDS FROM PENICILLIN SULFOXIDES. ETHYL 2-MERCAPTOACETATE

Micetich, Ronald G.,Maiti, Samarendra N.,Tanaka, Motoaki,Yamazaki, Tomio,Ogawa, Kazuo

, p. 3179 - 3182 (2007/10/02)

The thermolysis of trichloroethyl 6-phenoxyacetamido penicillanate sulfoxide and ethyl 2-mercaptoacetate in toluene gave the unsym-azetidinone disulfide (β,γ-isomer) in 65percent yield.With added catalytic amounts of N,N-dimethylaniline the α,β-isomer was
