Check Digit Verification of cas no

The CAS Registry Mumber 1260503-82-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,5,0 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1260503-82:
(9*1)+(8*2)+(7*6)+(6*0)+(5*5)+(4*0)+(3*3)+(2*8)+(1*2)=119
119 % 10 = 9
So 1260503-82-9 is a valid CAS Registry Number.

Rational electronic tuning of CBS catalyst for highly enantioselective borane reduction of trifluoroacetophenone

Korenaga, Toshinobu,Nomura, Kenji,Onoue, Kazutaka,Sakai, Takashi

, p. 8624 - 8626 (2011/01/03)

α,α,α-Trifluoroacetophenone (2), which is susceptible to noncatalytic reduction by BH3, could be reduced to chiral alcohol up to 90% ee by using electronically tuned-CBS catalyst (1) with BH3. The enantioselectivities highly correlated with the differential orbital energies between 1-BH3 adduct and 2, which were calculated by DFT method.
