Check Digit Verification of cas no

The CAS Registry Mumber 654681-20-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,4,6,8 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 654681-20:
(8*6)+(7*5)+(6*4)+(5*6)+(4*8)+(3*1)+(2*2)+(1*0)=176
176 % 10 = 6
So 654681-20-6 is a valid CAS Registry Number.

Exploring Tandem Ruthenium-Catalyzed Hydrogen Transfer and SNAr Chemistry

Polidano, Kurt,Reed-Berendt, Benjamin G.,Basset, Ana?s,Watson, Andrew J. A.,Williams, Jonathan M. J.,Morrill, Louis C.

, p. 6716 - 6719 (2017)

A hydrogen-transfer strategy for the catalytic functionalization of benzylic alcohols via electronic arene activation, accessing a diverse range of bespoke diaryl ethers and aryl amines in excellent isolated yields (38 examples, 70% average yield), is reported. Taking advantage of the hydrogen-transfer approach, the oxidation level of the functionalized products can be selected by judicious choice of simple and inexpensive additives.
