86307-44-0 Usage
Uses
Calcitriol (C144500) impurity. 1α-Hydroxyvitamin D and 1α-hydroxyprevitamin D compounds were prepared in multistep syntheses via hydroxylation of previtamin D compound adducts with dienophiles.
Check Digit Verification of cas no
The CAS Registry Mumber 86307-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,3,0 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 86307-44:
(7*8)+(6*6)+(5*3)+(4*0)+(3*7)+(2*4)+(1*4)=140
140 % 10 = 0
So 86307-44-0 is a valid CAS Registry Number.
