Check Digit Verification of cas no

The CAS Registry Mumber 10606-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,6,0 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10606-66:
(7*1)+(6*0)+(5*6)+(4*0)+(3*6)+(2*6)+(1*6)=73
73 % 10 = 3
So 10606-66-3 is a valid CAS Registry Number.

Enantio- and diastereoselective cyclopropanation with tert-butyl α-diazopropionate catalyzed by dirhodium(II) tetrakis[N- tetrabromophthaloyl-(S)-tert-leucinate]

supporting information; experimental part, p. 4200 - 4203 (2011/09/19)

The first successful example of a catalytic asymmetric cyclopropanation with α-diazopropionates is described. The cyclopropanation reaction of 1-aryl-substituted and related conjugated alkenes with tert-butyl α-diazopropionate has been achieved by catalysis with dirhodium(II) tetrakis[N-tetrabromophthaloyl-(S)-tert-leucinate], Rh2(S-TBPTTL) 4, providing the corresponding cyclopropane products containing a quarternary stereogenic center in good to high yields and with high diastereo- and enantioselectivities (trans:cis = 90:10 to >99:1, 81-93% ee).
