Check Digit Verification of cas no

The CAS Registry Mumber 1403327-88-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,3,2 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1403327-88:
(9*1)+(8*4)+(7*0)+(6*3)+(5*3)+(4*2)+(3*7)+(2*8)+(1*8)=127
127 % 10 = 7
So 1403327-88-7 is a valid CAS Registry Number.

Rhodium-catalyzed ring opening of benzocyclobutenols with site-selectivity complementary to thermal ring opening

Ishida, Naoki,Sawano, Shota,Masuda, Yusuke,Murakami, Masahiro

supporting information, p. 17502 - 17504,3 (2020/09/16)

A rhodium catalyst induced ring opening of benzocyclobutenols with selective cleavage of the C(sp2)-C(sp3) bond adjacent to the hydroxyl group. The site-selectivity markedly contrasted with that of their thermal ring-opening reaction. The rhodium-catalyzed ring opening led to the development of a new alkyne insertion reaction constructing a dihydronaphthalene framework.
