Check Digit Verification of cas no

The CAS Registry Mumber 81155-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,5 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81155-86:
(7*8)+(6*1)+(5*1)+(4*5)+(3*5)+(2*8)+(1*6)=124
124 % 10 = 4
So 81155-86-4 is a valid CAS Registry Number.

INTRINSIC MIGRATION APTITUDES OF ALKYL GROUPS IN A PINACOL REARRANGEMENT

Wistuba, Eckehardt,Ruechardt, Christoph

, p. 4069 - 4072 (1981)

From rates of solvolysis of substituted cis-2-tosyloxy-cyclopentanols 3 in sodium acetate buffered acetic acid the following relative migration aptitudes were deduced: H(171); CH3(6.7); C2H5(9.7); 2-C3H7(5.2); t-C4H9(2.5); C6H5(62).

Enantioselective titanium(III)-catalyzed reductive cyclization of ketonitriles

Streuff, Jan,Feurer, Markus,Bichovski, Plamen,Frey, Georg,Gellrich, Urs

supporting information; experimental part, p. 8661 - 8664 (2012/09/21)

Reduction, please! The title reaction affords ?-hydroxyketones, a common structural motif in biologically active natural products, in good yields and high enantioselectivities at room temperature. The commercially available ansa-titanocene 1 was found to be an efficient catalyst for this process, which presumably proceeds by addition of a ketyl radical to a nitrile.
