Check Digit Verification of cas no

The CAS Registry Mumber 1072123-37-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,2,1,2 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1072123-37:
(9*1)+(8*0)+(7*7)+(6*2)+(5*1)+(4*2)+(3*3)+(2*3)+(1*7)=105
105 % 10 = 5
So 1072123-37-5 is a valid CAS Registry Number.

supporting information; experimental part, p. 4887 - 4889 (2009/05/07)

(Chemical Equation Presented) A palladium(0)/monophosphine catalyst promotes a cyclization reaction of 2-(alkynyl)aryl isocyanates with organoboron reagents to produce stereodefined 3-alkylideneoxindoles. The alkynyl and isocyanato groups undergo oxidativ
