Check Digit Verification of cas no

The CAS Registry Mumber 112313-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,3,1 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112313-19:
(8*1)+(7*1)+(6*2)+(5*3)+(4*1)+(3*3)+(2*1)+(1*9)=66
66 % 10 = 6
So 112313-19-6 is a valid CAS Registry Number.

Thermal Cycloaddition of N-Arylmaleimides to Phenols: the Convenient Synthesis of Bicyclooct-2-en-5-one and Tricyclo2,8>octan-2-one Derivatives from Phenols

Bryce-Smith, Derek,Gilbert, Andrew,McColl, Ian S.,Drew, Michael G. B.,Yianni, Paul

, p. 1147 - 1152 (2007/10/02)

Monohydric phenols undergo 2,5-thermal cycloaddition of N-substituted maleimides to give bicyclooct-2-en-5-ones.Homopolymers of the maleimides are also concurrently formed, except in the case of N-(2,6-dimethylphenyl)maleimide: this is the preferred addend and gave a 63percent yield of the 2,5-adduct as a mixture of exo and endo isomers.U.v. irradiation in acetone of the diester (16) derived from the endo adduct of phenol and N-phenylmaleimide gave the tricyclo2,8>octan-3-one (17) in quantitative yield.
