Check Digit Verification of cas no

The CAS Registry Mumber 1293370-71-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,3,3,7 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1293370-71:
(9*1)+(8*2)+(7*9)+(6*3)+(5*3)+(4*7)+(3*0)+(2*7)+(1*1)=164
164 % 10 = 4
So 1293370-71-4 is a valid CAS Registry Number.

Preparation of α,β-unsaturated esters and amides via external-CO-free palladium-catalyzed carbonylation of alkenyl tosylates

Ueda, Tsuyoshi,Konishi, Hideyuki,Manabe, Kei

supporting information; experimental part, p. 5171 - 5175 (2012/09/25)

Palladium-catalyzed carbonylation of tosylates with phenyl formate is described. This procedure needs neither external carbon monoxide nor any pressure-resistant apparatus. A variety of cyclic and acyclic alkenyl tosylates can be converted into the corresponding phenyl esters in good yields. Furthermore, this method is effective for the one-pot synthesis of α,β-unsaturated amides.
