Check Digit Verification of cas no

The CAS Registry Mumber 221627-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,2 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 221627-40:
(8*2)+(7*2)+(6*1)+(5*6)+(4*2)+(3*7)+(2*4)+(1*0)=103
103 % 10 = 3
So 221627-40-3 is a valid CAS Registry Number.

Intramolecular palladium catalyzed alkoxy carbonylation of 6-hydroxy-1- octenes. Stereoselective synthesis of substituted tetrahydropyrans

White, James D.,Hong, Jian,Robarge, Lonnie A.

, p. 1463 - 1466 (1999)

The reaction of hydroxy alkenes 5, 7, and 8 with CO and MeOH in the presence of PdCl2 and CuCl2 gave tetrahydropyrans 9, 11, and 12, respectively. Yields were dependent upon the configuration of substituents in the hydroxy alkene; in all cases, the tetrahydropyran was produced with 2,6- cis configuration.
