130155-77-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130155-77-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,5 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130155-77:
(8*1)+(7*3)+(6*0)+(5*1)+(4*5)+(3*5)+(2*7)+(1*7)=90
90 % 10 = 0
So 130155-77-0 is a valid CAS Registry Number.

A photochemical route to 2-alkenyl- and 2-ethynylbenzofurans
Sumathi,Balasubramanian
, p. 3775 - 3778 (2007/10/02)
Intramolecular cyclisation of 1,5-biradicals generated by irradiation of o-alkenyloxy and o-alkynyloxy-benzophenones led to a facile synthesis of 2-alkenyl-3-phenyl and 2-ethynyl-3-phenylbenzofurans.
