Check Digit Verification of cas no

The CAS Registry Mumber 72050-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,5 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72050-61:
(7*7)+(6*2)+(5*0)+(4*5)+(3*0)+(2*6)+(1*1)=94
94 % 10 = 4
So 72050-61-4 is a valid CAS Registry Number.

Olefin Inversion. Protection of the Sulfide Function in the Stereospecific Sythesis of trans-Thiacyclooct-4-ene

Cere, Vanda,Guenzi, Alberto,Pollicino, Salvatore,Sandri, Edda,Fava, Antonino

, p. 261 - 264 (2007/10/02)

The concerted fragmentation method of Whitham has been applied to the configurational inversion of cis-thiacyclooct-4-ene (1) to give (35percent overall yield) trans-thiacyclooct-4-ene (2) of >98 percent configurational purity.The required protection of the S atom has been afforded by methylation, while deprotection was achieved by homogeneous LiAlH4 reduction in THF.Some peculiar NMR properties of the 1-methyl and 1-oxide derivatives of trans-thiacyclooctene are reported.
