Check Digit Verification of cas no

The CAS Registry Mumber 1028981-80-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,9,8 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1028981-80:
(9*1)+(8*0)+(7*2)+(6*8)+(5*9)+(4*8)+(3*1)+(2*8)+(1*0)=167
167 % 10 = 7
So 1028981-80-7 is a valid CAS Registry Number.

Sc(OTf)3-catalyzed or t-BuOK promoted tandem reaction of 2-(2-(alkynyl)benzylidene)malonate with indole

Gao, Ke,Wu, Jie

supporting information; experimental part, p. 2251 - 2254 (2009/05/26)

(Chemical Equation Presented) Tandem reaction of 2-(2-(alkynyl)benzylidene) malonate with indole was investigated. (Z)-1-Benzylidene-3-(1H-indol-1-yl)-1H- indene-2,2(3H)-dicarboxylate was generated in the presence of t-BuOK at room temperature; whereas 3-((1H-indol-3-yl)(2-(alkynyl)aryl)methyl)-1H-indole was obtained when Sc(OTf)3 was utilized as catalyst at 50°C.
