Check Digit Verification of cas no

The CAS Registry Mumber 1346019-21-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,0,1 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1346019-21:
(9*1)+(8*3)+(7*4)+(6*6)+(5*0)+(4*1)+(3*9)+(2*2)+(1*1)=133
133 % 10 = 3
So 1346019-21-3 is a valid CAS Registry Number.

Bronsted acid-promoted sequential hydroarylation-hydroamidation of arene-tethered 1-(2-alkynylphenyl)ureas: Direct access to 4,4-spiro-3,4-dihydro- 2-(1H)-quinazolinones

Wang, Honggen,Zhao, Jiaji,Zhang, Jiancun,Zhu, Qiang

supporting information; experimental part, p. 2653 - 2658 (2011/12/01)

A Bronsted acid-promoted approach to 4,4-sipro-3,4-dihydro-2-(1H)- quinazolinones from arene-tethered 1-(2-alkynylphenyl)ureas has been developed. The reaction is initiated by intramolecular hydroarylation followed by hydroamidation, assisted by intramole
