Check Digit Verification of cas no

The CAS Registry Mumber 857058-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,0,5 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 857058-58:
(8*8)+(7*5)+(6*7)+(5*0)+(4*5)+(3*8)+(2*5)+(1*8)=203
203 % 10 = 3
So 857058-58-3 is a valid CAS Registry Number.

Ogawa, Yasuyuki,Kuroda, Kiichi,Mukaiyama, Teruaki

, p. 698 - 699 (2007/10/03)

δ,β′-Dihydroxy-β,γ-unsaturated esters were stereoselectively synthesized by aldol reaction of aldehydes with samarium enolates that were generated by epoxide-fragmentation of γ,δ- oxiranyl-α,β-unsaturated esters using two moles of samarium(II) iodide. Thi
