Check Digit Verification of cas no

The CAS Registry Mumber 307966-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,9,6 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 307966-23:
(8*3)+(7*0)+(6*7)+(5*9)+(4*6)+(3*6)+(2*2)+(1*3)=160
160 % 10 = 0

Experimental evidence for negative hyperconjugation as a component of the polar effect: Variation of the ease of α-sulfonyl carbanion formation with the orientation of a β-alkoxy substituent

King, James F.,Rathore, Rajendra,Guo, Zhenrong,Li, Manqing,Payne, Nicholas C.

, p. 10308 - 10324 (2007/10/03)

We report evidence for a strongly geometry-dependent substituent effect. The rate constants for H-D exchange of the α-hydrogens, (k(exch))OR, in a set of 19 β-alkoxy sulfones of known, fixed (or strongly preferred) H-C(α)-C(β)-OR torsion angles have been
