Check Digit Verification of cas no

The CAS Registry Mumber 54482-41-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,4,8 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54482-41:
(7*5)+(6*4)+(5*4)+(4*8)+(3*2)+(2*4)+(1*1)=126
126 % 10 = 6
So 54482-41-6 is a valid CAS Registry Number.

INSERTION OF OXYGEN ATOM IN STEROID FRAMEWORKS -- A NEW METHOD OF TRANSFORMATION OF HYDROXYSTEROID INTO OXASTEROID

Suginome, Hiroshi,Yamada, Shinji

, p. 1233 - 1236 (1982)

A two-step transformation of saturated hydroxysteroids into oxasteroids is described; the reaction involves photo-reaction of the hypoiodites of the hydroxysteroids generated with mercury(II) oxide and iodine to give isomeric formyl esters , which are cyclized to oxasteroids with sodium borohydride.

Synthesis and Photoreaction of D-Nor-5α-androstan-16-one Acetylhydrazone in the Presence of Oxygen
