Check Digit Verification of cas no

The CAS Registry Mumber 1175540-19-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,5,5,4 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1175540-19:
(9*1)+(8*1)+(7*7)+(6*5)+(5*5)+(4*4)+(3*0)+(2*1)+(1*9)=148

Palladium-catalyzed coupling of ortho-alkynylanilines with terminal alkynes under aerobic conditions: Efficient synthesis of 2,3-disubstituted 3-alkynylindoles

Yao, Bo,Wang, Qian,Zhu, Jieping

supporting information, p. 12311 - 12315 (2013/02/23)

Two nucleophiles, one triple bond: Under aerobic conditions, palladium-catalyzed direct coupling of o-alkynylanilines and terminal alkynes took place smoothly to afford the 2,3-disubstituted 3-alkynylindoles 3 in good to excellent yields. The intermediate A was characterized and a retro-aminopalladation of B was observed for the first time. Copyright
