Check Digit Verification of cas no

The CAS Registry Mumber 1573209-51-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,3,2,0 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1573209-51:
(9*1)+(8*5)+(7*7)+(6*3)+(5*2)+(4*0)+(3*9)+(2*5)+(1*1)=164
164 % 10 = 4
So 1573209-51-4 is a valid CAS Registry Number.

Highly functionalized pyridines synthesis from N-sulfonyl ketimines and alkynes using the N-S bond as an internal oxidant

Zhang, Qian-Ru,Huang, Ji-Rong,Zhang, Wei,Dong, Lin

, p. 1684 - 1687 (2014/04/17)

The N-S bond-based internal oxidant offers a distinct approach for the synthesis of highly functionalized pyridines. A novel Rh(III)-catalyzed one-pot process undergoes an efficient C-C/C-N bond formation along with desulfonylation under very mild conditions. The method is quite simple, general, and efficient.
