Check Digit Verification of cas no

The CAS Registry Mumber 660394-73-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,0,3,9 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 660394-73:
(8*6)+(7*6)+(6*0)+(5*3)+(4*9)+(3*4)+(2*7)+(1*3)=170
170 % 10 = 0
So 660394-73-0 is a valid CAS Registry Number.

2,4,6-trialkylphenyl-2H-phospholes from slightly aromatic 1H-phospholes and their use in [4 + 2] cycloaddition reactions

Keglevich, Gyoergy,Farkas, Renata,Imre, Timea,Ludanyi, Krisztina,Szoellosy, Aron,Toke, Laszlo

, p. 316 - 319 (2003)

1-(2,4,6-Trialkylphenyl) phosphates 1a,b possess a moderate aromatic character. Despite of that they underwent a sigmatropic rearrangement at 150°C to afford 2H-phospholes 2a,b which by trapping with tolane, or in reaction with another unit of 2 gave [4 +
