Check Digit Verification of cas no

The CAS Registry Mumber 92115-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,1 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92115-08:
(7*9)+(6*2)+(5*1)+(4*1)+(3*5)+(2*0)+(1*8)=107
107 % 10 = 7
So 92115-08-7 is a valid CAS Registry Number.

Transitional-Metal-Activated Organic Compounds, XXXV. - ortho-Alkylation of Aromatic Azo Compounds with Alkyllithium Reagents and Lithium Trimethylferrate(1-)

Kauffmann, Thomas,Jordan, Jan,Sander, Joerg

, p. 153 - 155 (2007/10/02)

Whereas methyllithium reacts with 4-(dimethylamino)-, 4-amino-, and 4-methoxyazobenzene, respectively, by ortho-methylation of the electron-rich phenyl residue of the azo compound, (CH3)3FeLi ortho-methylates the less electron-rich phenyl group of 4-(dimethylamino)azobenzene.A mechanistic rationalization is given for both reaction modes.Key Words: Lithium, organo compounds / Iron, organo compounds / Azo compounds / ortho-Alkylation
