222535-39-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222535-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,5,3 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 222535-39:
(8*2)+(7*2)+(6*2)+(5*5)+(4*3)+(3*5)+(2*3)+(1*9)=109
109 % 10 = 9
So 222535-39-9 is a valid CAS Registry Number.

4,4-Difluoro-1α,25-dihydroxyvitamin D3: Analog to probe A-ring conformation in vitamin D-receptor complex
Shimizu, Masato,Iwasaki, Yukiko,Yamada, Sachiko
, p. 1697 - 1700 (2007/10/03)
4,4-Difluoro-1α,25-dihydroxyvitamin D3 was synthesized from ergosterol and analysis of its 19F NMR showed it to be a useful probe to analyze the receptor-bound A-ring conformation of vitamin D.
