145223-33-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 145223-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,2 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145223-33:
(8*1)+(7*4)+(6*5)+(5*2)+(4*2)+(3*3)+(2*3)+(1*3)=102
102 % 10 = 2
So 145223-33-2 is a valid CAS Registry Number.

A nitrile approach to the synthesis of the side chain of vitamin D metabolites and analogues

Fall,Torneiro,Castedo,Mourino

, p. 6683 - 6686 (1992)

An efficient new method for the construction of vitamin D hydroxylated side chains is described which is based on the alkylation and opening of epoxides by the α-anions derived from nitriles 6 and 7.
