The CAS Registry Mumber 440090-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,0,9 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 440090-07:
(8*4)+(7*4)+(6*0)+(5*0)+(4*9)+(3*0)+(2*0)+(1*7)=103
103 % 10 = 3
So 440090-07-3 is a valid CAS Registry Number.

A synthesis of 6-tributylstannyl-3,4-dihydro-2H-pyrans via coupling of enol triflates with (Bu3Sn)(Bu)Culi·liCN

Wildman, Tanya,Kocienski, Philip J.,Narquizian, Robert,Whittingham, William G.

, p. 393 - 398 (2007/10/03)

Enol triflates derived from 6- and 7-membered ring lactones (6 cases) react with (Bu3Sn)(Bu)CuLi·LiCN in THF at -78 °C to give the corresponding α-tributylstannyl cyclic enol ethers in 54-85% yield.
