The CAS Registry Mumber 1207666-91-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,6,6 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1207666-91:
(9*1)+(8*2)+(7*0)+(6*7)+(5*6)+(4*6)+(3*6)+(2*9)+(1*1)=158
158 % 10 = 8
So 1207666-91-8 is a valid CAS Registry Number.

The effect of substrate structure on the direction of cyclization of ortho-alkynylbenzene diazonium salts

Fedenok, Lidiya G.,Shvartsberg, Mark S.,Bashurova, Valentina S.,Bogdanchikov, George A.

, p. 67 - 69 (2010)

The cyclization of ortho-(arylethynyl)benzene diazonium salts (the Richter reaction) is studied. A reaction mechanism, which differs radically from that reported earlier is proposed and substantiated by experimental data and quantum-chemical calculations.
