Check Digit Verification of cas no

The CAS Registry Mumber 1239316-25-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,3,1 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1239316-25:
(9*1)+(8*2)+(7*3)+(6*9)+(5*3)+(4*1)+(3*6)+(2*2)+(1*5)=146
146 % 10 = 6
So 1239316-25-6 is a valid CAS Registry Number.

A multi-task palladium catalyst involved in heck-reduction-cyclization sequences for the preparation of 4-benzyl-1,2-dihydroisoquinolin-3-ones: An unusual homogeneous-heterogeneous sustainable approach

Laudien, Julia,Fouquet, Eric,Zakri, Cécile,Felpin, Fran?ois-Xavier

experimental part, p. 1539 - 1543 (2010/08/22)

A mixed homogeneous-heterogeneous catalysis that exploits a multi-task palladium catalyst has been developed for one-pot sequential Heck-reduction-cyclization (HRC) reactions leading to novel 4-benzyl-1,2- dihydroisoquinolin-3-ones. The HRC sequence requires mild conditions and allows the separation of the palladium residues under the form of an in situ generated Pd(0)/C catalyst by simple filtration. The homemade and recovered catalyst can be efficiently reused for Suzuki-Miyaura reactions and reductive processes making it useful for sustainable chemistry. Georg Thieme Verlag Stuttgart New York.
