Check Digit Verification of cas no

The CAS Registry Mumber 154355-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,5 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 154355-80:
(8*1)+(7*5)+(6*4)+(5*3)+(4*5)+(3*5)+(2*8)+(1*0)=133
133 % 10 = 3
So 154355-80-3 is a valid CAS Registry Number.

Intra- and Intermolecular Nickel-Catalyzed Reductive Cross-Electrophile Coupling Reactions of Benzylic Esters with Aryl Halides

Konev, Mikhail O.,Hanna, Luke E.,Jarvo, Elizabeth R.

supporting information, p. 6730 - 6733 (2016/06/09)

Nickel-catalyzed cross-electrophile coupling reactions of benzylic esters and aryl halides have been developed. Both inter- and intramolecular variants proceed under mild reaction conditions. A range of heterocycles and functional groups are tolerated under the reaction conditions. Additionally, the first example of a stereospecific cross-electrophile coupling of a secondary benzylic ester is described.
