Check Digit Verification of cas no

The CAS Registry Mumber 1213268-41-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,2,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1213268-41:
(9*1)+(8*2)+(7*1)+(6*3)+(5*2)+(4*6)+(3*8)+(2*4)+(1*1)=117
117 % 10 = 7
So 1213268-41-7 is a valid CAS Registry Number.

supporting information; experimental part, p. 1961 - 1966 (2010/06/20)

"Chemical Equation Presented" An efficient and highly regioselective protocol was developed for the preparation of 5-hydroxy2-isoxazolines, which have been proved to be versatile synthons for isoxazles, β-hydroxy oximes, and γ-amino alcohols. β-Lactams, commonly embedded in the skeletons of bioactive natural products, were also synthesized in two steps from β-hydroxy oximes, providing a new strategy for the synthesis of this kind of compounds.
