Check Digit Verification of cas no

The CAS Registry Mumber 1280135-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,1,3 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1280135-91:
(9*1)+(8*2)+(7*8)+(6*0)+(5*1)+(4*3)+(3*5)+(2*9)+(1*1)=132
132 % 10 = 2
So 1280135-91-2 is a valid CAS Registry Number.

Studies on the intermolecular hydroarylation of N-Ts- or N-Ac-protected indoles and 2,3-allenoates

Fang, Zhao,Fu, Chunling,Ma, Shengming

supporting information; experimental part, p. 1227 - 1231 (2011/04/15)

An operationally simple, TFA-promoted regioselective hydroarylation reaction of 2,3-allenoates with N-Ts- or N-Ac-indoles to afford 4-indolyl-4-arylbut-2-enoates is described. A series of substrates was tested, and the E/Z selectivity was found to depend
