Check Digit Verification of cas no

The CAS Registry Mumber 672939-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,9,3 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 672939-89:
(8*6)+(7*7)+(6*2)+(5*9)+(4*3)+(3*9)+(2*8)+(1*9)=218
218 % 10 = 8
So 672939-89-8 is a valid CAS Registry Number.

, p. 683 - 685 (2007/10/03)

Phase-selective photochemical reaction of 2-pyridone derivatives was examined. Irradiation of 1 in benzene mainly gave rearrangement products 2. However, intermolecular [4 + 4] photocycloaddition proceeded quantitatively in the solid state, affording phot
