Check Digit Verification of cas no

The CAS Registry Mumber 68170-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,7 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68170-81:
(7*6)+(6*8)+(5*1)+(4*7)+(3*0)+(2*8)+(1*1)=140
140 % 10 = 0
So 68170-81-0 is a valid CAS Registry Number.

REGIOSELECTIVE REDUCTION OF POLYKETONES ON SILICA GEL SURFACE WITH BORANE-TRIMETHYLAMINE COMPLEX

Gohzu, Shun-ichi,Tada, Masahiro

, p. 61 - 64 (1986)

Steroidal diones and trione, bicyclic diones (7 and 8) and a tricyclic dione were adsorbed on silica gel and reduced with BH3*NMe3.The carbonyl groups at C-3 of the steroids, at C-4 of 7 and at C-3 of 8 were reduced regioselectively.The FT-IR spectra of 5α- and 5β-androstane-3,17-dione adsorbed on silica gel were measured.
