Check Digit Verification of cas no

The CAS Registry Mumber 138852-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,5 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138852-17:
(8*1)+(7*3)+(6*8)+(5*8)+(4*5)+(3*2)+(2*1)+(1*7)=152
152 % 10 = 2
So 138852-17-2 is a valid CAS Registry Number.

An Improved Synthesis of 1α-hydroxy Vitamin D3

Nerinckx, W.,Clercq, P. J. De,Couwenhoven, C.,Overbeek, W. R. M.,Halkes, S. J.

, p. 9419 - 9430 (1991)

The efficient and stereoselective introduction of the 1α-OH function in vitamin D3 is described starting from the known previtamin D3 adduct 6.The sequence involves the stereoselective allylic bromination to 9, followed by substituti
