121809-01-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121809-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,0 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121809-01:
(8*1)+(7*2)+(6*1)+(5*8)+(4*0)+(3*9)+(2*0)+(1*1)=96
96 % 10 = 6
So 121809-01-6 is a valid CAS Registry Number.

Evidence for the importance of π-π attractive interactions in enantioselective Diels-Alder reactions chiral catalysts of type (RO)2TiCl2

Corey,Matsumura

, p. 6289 - 6292 (2007/10/02)

Reaction of diol 4 with Ti(O i-Pr)4 followed by SiCl4 results in formation of the Ti (IV) complex 5 which is an exceptionally effective catalyst for enantioselective Diels-Alder reactions. The origin of the high enantioselectivities
