Check Digit Verification of cas no

The CAS Registry Mumber 82067-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,6 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82067-20:
(7*8)+(6*2)+(5*0)+(4*6)+(3*7)+(2*2)+(1*0)=117
117 % 10 = 7
So 82067-20-7 is a valid CAS Registry Number.

Regioselective Lithiation and Substitution of Tricarbonyl-(η6-1-methylindole)chromium(0): X-Ray Crystal Structure Analysis of Tricarbonyl-(η6-1-methyl-2-trimethylsilyl-7-ethoxycarbonylindole)chromium(0)

Nechvatal, Gordon,Widdowson, David A.,Williams, David J.

, p. 1260 - 1262 (2007/10/02)

Tricarbonyl(η6-1-methylindole)chromium(0) is lithiated by n-butyl-lithium at C-2 whereas tricarbonyl-(η6-1-methyl-2-trimethylsilylindole)chromium(0) is lithiated predominantly at C-7, as shown by X-ray analysis of the derived 7-ethoxycarbonyl derivative, and the 7-lithio species is substituted in good yield by a range of electrophiles.
