Check Digit Verification of cas no

The CAS Registry Mumber 1218917-39-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,9,1 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1218917-39:
(9*1)+(8*2)+(7*1)+(6*8)+(5*9)+(4*1)+(3*7)+(2*3)+(1*9)=165
165 % 10 = 5
So 1218917-39-5 is a valid CAS Registry Number.

Asymmetric counteranion-directed transition-metal catalysis: Enantioselective epoxidation of alkenes with Manganese(III) salen phosphate complexes

Liao, Saihu,List, Benjamin

, p. 628 - 631 (2010)

(Figure Presented) Figure Presentation Paired up: A highly active and enantioselective ion-pair epoxidation catalyst, consisting of an achiral Mn |||-salen complex and a chiral phosphate counteranion, mediates the epoxidization of a wide range of alkenes with high yields and enantioselectivities (see scheme). The unique role of the counteranion is to stabilize an enantiomorphic conformation of the cationic Mn catalyst.
