Check Digit Verification of cas no

The CAS Registry Mumber 1187817-62-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,8,1 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1187817-62:
(9*1)+(8*1)+(7*8)+(6*7)+(5*8)+(4*1)+(3*7)+(2*6)+(1*2)=194
194 % 10 = 4
So 1187817-62-4 is a valid CAS Registry Number.

Lewis Acid Activation of a Hydrogen Bond Donor Metal-Organic Framework for Catalysis

Hall, Edward A.,Redfern, Louis R.,Wang, Michael H.,Scheidt, Karl A.

, p. 3248 - 3252 (2016/07/06)

A new metal-organic framework (MOF) composed of urea-containing tetracarboxylate struts was synthesized, and its hydrogen bonding capabilities were evaluated. The catalytic performance of this heterogeneous framework is enhanced through preactivation with silyl Lewis acids, leading to Friedel-Crafts reaction rates greater than those of common homogeneous hydrogen bond donors.
