Check Digit Verification of cas no

The CAS Registry Mumber 1338700-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,7,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1338700-21:
(9*1)+(8*3)+(7*3)+(6*8)+(5*7)+(4*0)+(3*0)+(2*2)+(1*1)=142
142 % 10 = 2
So 1338700-21-2 is a valid CAS Registry Number.

Palladium-catalyzed selective carboelimination and cross-coupling reactions of benzocyclobutenols with aryl bromides

Chtchemelinine, Andrei,Rosa, David,Orellana, Arturo

supporting information; experimental part, p. 9157 - 9162 (2011/12/16)

The palladium-catalyzed selective β-carboelimination and cross-coupling chemistry of benzocyclobutenols is described. In contrast to the base-mediated ring-opening reactions of benzocyclobutenols, this variant proceeds with exclusive cleavage of the proximal bond.
