Check Digit Verification of cas no

The CAS Registry Mumber 1644565-58-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,4,5,6 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1644565-58:
(9*1)+(8*6)+(7*4)+(6*4)+(5*5)+(4*6)+(3*5)+(2*5)+(1*8)=191
191 % 10 = 1
So 1644565-58-1 is a valid CAS Registry Number.

supporting information, p. 5805 - 5810 (2017/07/22)

An efficient solvent-free protocol for the Buchwald-Hartwig cross-coupling reaction of aryl and heteroaryl chlorides with primary and secondary amines using the Pd(dba)2/ligand 1 catalytic system has been developed. Notably, the catalytic system also efficiently catalyzed the reaction under aqueous conditions.
