Check Digit Verification of cas no

The CAS Registry Mumber 82297-68-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,9 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 82297-68:
(7*8)+(6*2)+(5*2)+(4*9)+(3*7)+(2*6)+(1*8)=155
155 % 10 = 5
So 82297-68-5 is a valid CAS Registry Number.

Organocatalyzed Asymmetric Conjugate Addition of Heteroaryl and Aryl Trifluoroborates: A Synthetic Strategy for Discoipyrrole D

Shih, Jiun-Le,Nguyen, Thien S.,May, Jeremy A.

supporting information, p. 9931 - 9935 (2015/08/19)

Bis-heteroaryl or bis-aryl stereocenters were formed by an organocatalytic enantioselective conjugate addition using the respective trifluoroborate salts as nucleophiles. Control studies suggested that fluoride dissociation is necessary in the anhydrous conditions. This strategy is applicable to the synthesis of discoipyrrole D, an inhibitor of BR5 fibroblast migration.
