Check Digit Verification of cas no

The CAS Registry Mumber 75431-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,3 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75431-25:
(7*7)+(6*5)+(5*4)+(4*3)+(3*1)+(2*2)+(1*5)=123
123 % 10 = 3
So 75431-25-3 is a valid CAS Registry Number.

Efficient Coupling of Tertiary Alkyl Halides with Dialkylzinc and Titanium Compounds

Reetz, Manfred T.,Wenderoth, Bernd,Peter, Roland,Steinbach, Rainer,Westermann, Juergen

, p. 1202 - 1204 (2007/10/02)

Dialkylzinc compounds react with tertiary halides to afford the corresponding coupling products containing a quaternary carbon atom, thereby making geminal dialkylation of ketones or hydroalkylation of olefins possible.
