Check Digit Verification of cas no

The CAS Registry Mumber 171925-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,9,2 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 171925-98:
(8*1)+(7*7)+(6*1)+(5*9)+(4*2)+(3*5)+(2*9)+(1*8)=157
157 % 10 = 7
So 171925-98-7 is a valid CAS Registry Number.

A Stereocontrolled Route to Both Enantiomers of the Necine Base Dihydroxyheliotridane via Intramolecular 1,3-Dipolar Addition Using the Same Chiral Precursor

Hashimura, Kazuya,Tomita, Shun'ichi,Hiroya, Kou,Ogasawara, Kunio

, p. 2291 - 2292 (2007/10/02)

Diastereofacial selectivity in an enantiospecific intramolecular 1,3-dipolar addition is controlled by adjusting the size of the tether between the dipole and the dipolarophile to give 2,3-disubstituted pyrrolidines enantiomeric with respect to the newly
