Check Digit Verification of cas no

The CAS Registry Mumber 334022-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,0,2 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 334022-49:
(8*3)+(7*3)+(6*4)+(5*0)+(4*2)+(3*2)+(2*4)+(1*9)=100
100 % 10 = 0
So 334022-49-0 is a valid CAS Registry Number.

Catalytic enantioselective cyanosilylation of ketones: Improvement of enantioselectivity and catalyst turn-over by ligand tuning

Hamashima, Yoshitaka,Kanai, Motomu,Shibasaki, Masakatsu

, p. 691 - 694 (2007/10/03)

Sterical and electronical tuning of the bifunctional catalyst 1 afforded the improved catalyst 2, which promoted the cyanosilylation of ketones with higher enantioselectivity as well as with improved catalyst turn-over with a factor of up to 10. Thus, chiral quaternary α-hydroxynitriles were obtained with excellent ee (up to 94% ee) using 1 mol% of 2 in the case of aryl ketones and 2.5 mol% of 2 in the case of aliphatic ketones.
