Check Digit Verification of cas no

The CAS Registry Mumber 1259948-29-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,9,4 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1259948-29:
(9*1)+(8*2)+(7*5)+(6*9)+(5*9)+(4*4)+(3*8)+(2*2)+(1*9)=212
212 % 10 = 2
So 1259948-29-2 is a valid CAS Registry Number.

Tandem transformations of tetrahydrobenzothieno[2,3-c]pyridines in the presence of activated alkynes

Voskressensky, Leonid G.,Kovaleva, Svetlana A.,Borisova, Tatiana N.,Listratova, Anna V.,Eresko, Alexandr B.,Tolkunov, Valery S.,Tolkunov, Sergey V.,Varlamov, Alexey V.

experimental part, p. 9421 - 9430 (2011/01/12)

The reactivity of some new tetrahydrothienopyridines towards activated alkynes was investigated. A novel cascade cleavage-spiroannulation process, leading to the formation of previously unreported derivatives of 1′H-spiro[1-benzothiophene-3,4′-pyridine] was discovered and studied.
