Check Digit Verification of cas no

The CAS Registry Mumber 244249-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,2,4 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 244249-00:
(8*2)+(7*4)+(6*4)+(5*2)+(4*4)+(3*9)+(2*0)+(1*0)=121
121 % 10 = 1
So 244249-00-1 is a valid CAS Registry Number.

Treatment of CpW(CO)3[η1-CH2C≡C(CH 2)n-Ar] (n = 0-1) with triflic acid catalysts (25 mol %) in cold CH2Cl2 (-95 °C) effects a new cyclocarbonylation reaction to give CpW(CO)2(π-cyclopentenonyl) and CpW(CO)2(π-cyclohexenonyl) compounds; these results provide direct evidence for addition of neutral aryl C-H bonds to coordinated carbonyl groups.
