Check Digit Verification of cas no

The CAS Registry Mumber 1570511-03-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,0,5,1 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1570511-03:
(9*1)+(8*5)+(7*7)+(6*0)+(5*5)+(4*1)+(3*1)+(2*0)+(1*3)=133
133 % 10 = 3
So 1570511-03-3 is a valid CAS Registry Number.

A catalytic enantiotopic-group-selective Suzuki reaction for the construction of chiral organoboronates

Sun, Chunrui,Potter, Bowman,Morken, James P.

supporting information, p. 6534 - 6537 (2014/05/20)

Catalytic enantiotopic-group-selective cross-couplings of achiral geminal bis(pinacolboronates) provide a route for the construction of nonracemic chiral organoboronates. In the presence of a chiral monodentate taddol-derived phosphoramidite ligand, these reactions occur with high levels of asymmetric induction. Mechanistic experiments with chiral 10B-enriched geminal bis(boronates) suggest that the reaction occurs by a stereochemistry-determining transmetalation that occurs with inversion of configuration at carbon.
