858458-42-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 858458-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,4,5 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 858458-42:
(8*8)+(7*5)+(6*8)+(5*4)+(4*5)+(3*8)+(2*4)+(1*2)=221
221 % 10 = 1
So 858458-42-1 is a valid CAS Registry Number.

supporting information; experimental part, p. 4136 - 4139 (2012/06/01)

Vanishing aromaticity: A chiral ruthenium complex catalyzes the hydrogenation of 2,6- or 2,7-disubstituted naphthalenes to give chiral tetralins with up to 92 % ee. The chiral catalyst is applicable to the regio- and enantioselective reduction of 6-substi
