Check Digit Verification of cas no

The CAS Registry Mumber 210701-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,7,0 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 210701-06:
(8*2)+(7*1)+(6*0)+(5*7)+(4*0)+(3*1)+(2*0)+(1*6)=67
67 % 10 = 7
So 210701-06-7 is a valid CAS Registry Number.

Synthesis of optically active cyclopenta[b]benzofuran as a precursor of m-phenyleneprostacyclin

Nishiyama, Hisao,Sakata, Naoya,Sugimoto, Hayato,Motoyama, Yukihiro,Wakita, Hisanori,Nagase, Hiroshi

, p. 930 - 932 (2007/10/03)

The optically pure cyclopenta[b]benzofuran derivatives (-)-1 and (-)-2 were synthesized from (+)-(1S,4R)-cis-4-acetoxy-2-cyclopenten-1-ol [(+)-3] via sequential Mitsunobu reaction and palladium-catalyzed allylic substitution with phenol derivatives followed by SN2′ intramolecular cyclization.
