Check Digit Verification of cas no

The CAS Registry Mumber 114826-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,8,2 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 114826-26:
(8*1)+(7*1)+(6*4)+(5*8)+(4*2)+(3*6)+(2*2)+(1*6)=115
115 % 10 = 5
So 114826-26-5 is a valid CAS Registry Number.

STEREOSELECTIVE REDUCTION OF C-2 SUBSTITUTED STEROID C-3 KETONES WITH LITHIUM TRIS-(R,S-1,2-DIMETHYLPROPYL)-BOROHYDRIDE AND SODIUM BOROHYDRIDE

Templeton, John F.,Kumar, V. P. Sashi,Gupta, R. K.,Friesen, Anne M.

, p. 339 - 346 (2007/10/02)

The effect of C-2 substitution on the stereoselective reduction of steroid C-3 ketones with lithium tris(R,S-1,2-dimethylpropyl)-borohydride and sodium borohydride was investigated.The C-2 mono- and di-substituted chloro and methyl derivatives were predominantly reduced to one of the epimeric alcohols.The 2α-chloro and 2α-methyl derivatives of 17β-acetoxy-5α-androstan-3-one undergo stereoselective reduction with lithium tris (R,S-1,2-dimethylpropyl)-borohydride to the axial (3α) alcohol as observed in the unsubstituted compound, whereas sodium borohydride gives predominantly the equatorial (3β) alcohol.The 2β-chloro, 2β-methyl, 2,2-dichloro, and 2,2-dimethyl derivatives are reduced predominantly to the equatorial (3β) alcohol by both reagents.
