Check Digit Verification of cas no

The CAS Registry Mumber 28199-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,9 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28199-00:
(7*2)+(6*8)+(5*1)+(4*9)+(3*9)+(2*0)+(1*0)=130
130 % 10 = 0
So 28199-00-0 is a valid CAS Registry Number.

Base and Acid Catalysis by the Alkali-containing MCM-41 Mesoporous Molecular Sieve

Kloetstra, K. Richard,Bekkum, Herman van

, p. 1005 - 1006 (1995)

Sodium and caesium cation-exchanged mesoporous MCM-41 are shown to be mild, selective, water-stable and recyclable catalysts for the base-catalysed Knoevenagel condensation and acid-catalysed acetalization and aldol condensation, whereas caesium acetate-impregnated MCM-41 shows strong base activity in the Michael addition.
