Check Digit Verification of cas no

The CAS Registry Mumber 93681-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,8 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93681-54:
(7*9)+(6*3)+(5*6)+(4*8)+(3*1)+(2*5)+(1*4)=160
160 % 10 = 0
So 93681-54-0 is a valid CAS Registry Number.

Diverse Visible-Light-Promoted Functionalizations of Benzotriazoles Inspired by Mechanism-Based Luminescence Screening

Teders, Michael,Gómez-Suárez, Adrián,Pitzer, Lena,Hopkinson, Matthew N.,Glorius, Frank

supporting information, p. 902 - 906 (2017/01/13)

Three new visible-light-promoted functionalizations of benzotriazole substrates were discovered using a mechanism-based screening method. ortho-Thiolated, borylated, and alkylated N-arylbenzamide products were obtained under mild reaction conditions in a new denitrogenative synthetic approach to functionalized aniline derivatives. The functional group tolerance of the borylation reaction was further analyzed in the first application of an additive-based robustness screen in a photocatalytic transformation. All the functionalizations proceed via photocatalytically initiated chain mechanisms as indicated by determination of the reaction quantum yields and Stern–Volmer analyses.
