Check Digit Verification of cas no

The CAS Registry Mumber 1044220-91-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,2,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1044220-91:
(9*1)+(8*0)+(7*4)+(6*4)+(5*2)+(4*2)+(3*0)+(2*9)+(1*1)=98
98 % 10 = 8
So 1044220-91-8 is a valid CAS Registry Number.

Regioselective synthesis of pyrano[3,2-c]pyrimidine derivatives via a palladium-catalyzed unusual [1,3] aryloxy shift and cycloisomerization: first report of a [1,3] shift of an aryloxy group

Majumdar,Sinha,Chattopadhyay,Ray

, p. 4405 - 4408 (2008/12/21)

Uracil-annulated pyrano heterocycles are regioselectively synthesized in excellent yields (92-100%) via a palladium-catalyzed unusual [1,3] aryloxy shift followed by 6-endo dig cyclization and [1,3] prototropic shift.
