Check Digit Verification of cas no

The CAS Registry Mumber 34940-01-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,9,4 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34940-01:
(7*3)+(6*4)+(5*9)+(4*4)+(3*0)+(2*0)+(1*1)=107
107 % 10 = 7
So 34940-01-7 is a valid CAS Registry Number.

Enantioselective construction of quaternary stereogenic centers from tertiary boronic esters: Methodology and applications

Sonawane, Ravindra P.,Jheengut, Vishal,Rabalakos, Constantinos,Larouche-Gauthier, Robin,Scott, Helen K.,Aggarwal, Varinder K.

supporting information; experimental part, p. 3760 - 3763 (2011/06/22)

Pin it down: A range of substrates that bear versatile functional groups with quaternary stereogenic centers have been prepared with very high enantioselectivity from tertiary boronic esters (see scheme; Cb=N,N-diisopropylcarbamoyl, pin=pinacolato). The preparation of allylboronic esters bearing contiguous quaternary and tertiary stereogenic centers, and applications to natural product synthesis are also reported.
