162636-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162636-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,6,3 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 162636-76:
(8*1)+(7*6)+(6*2)+(5*6)+(4*3)+(3*6)+(2*7)+(1*6)=142
142 % 10 = 2
So 162636-76-2 is a valid CAS Registry Number.

(10Z)- and (10E)-19-fluoro-1 α,25-dihydroxyvitamin D3: An improved synthesis via 19-nor-10-oxo-vitamin D
Shimizu,Ohno,Yamada
, p. 312 - 317 (2007/10/03)
An efficient synthetic route to (10Z)- and (10E)-19-fluoro-1α,25-dihydroxyvitamin D3 was developed. The key feature of this pathway is the introduction of a 19-fluoromethylene group to a (5E)-19-nor-10-oxo-vitamin D derivative. The 10-oxo-compo
