Check Digit Verification of cas no

The CAS Registry Mumber 1182020-85-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,2,0,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1182020-85:
(9*1)+(8*1)+(7*8)+(6*2)+(5*0)+(4*2)+(3*0)+(2*8)+(1*5)=114
114 % 10 = 4
So 1182020-85-4 is a valid CAS Registry Number.

New route to 2-arylthieno[2,3-d]pyrimidin-4(3H)-ones and isolation of the unoxidized intermediates

Davoodnia, Abolghasem,Bakavoli, Mehdi,Soleimany, Mehdi,Tavakoli-Hoseini, Niloofar

, p. 355 - 358 (2009)

A new route to the synthesis of 2-arylthieno[2,3-d]pyrimidin-4(3H)-ones has been developed through heterocyclization of 2-amino-4,5-dimethylthiophene-3- carboxamide with aromatic aldehydes in boiling glacial acetic acid followed by air oxidation. The unox
