905919-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 905919-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,9,1 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 905919-70:
(8*9)+(7*0)+(6*5)+(5*9)+(4*1)+(3*9)+(2*7)+(1*0)=192
192 % 10 = 2
So 905919-70-2 is a valid CAS Registry Number.

Asymmetric [3 + 2] annulations catalyzed by a planar-chiral derivative of DMAP
Bappert, Erhard,Mueller, Peter,Fu, Gregory C.
, p. 2604 - 2606 (2006)
A planar-chiral DMAP derivative catalyzes an intriguing [3 + 2] annulation reaction of silylated indenes to produce diquinanes that bear three contiguous stereocenters (one quaternary and two tertiary). The Royal Society of Chemistry 2006.
