38819-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 38819-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,8,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 38819-44:
(7*3)+(6*8)+(5*8)+(4*1)+(3*9)+(2*4)+(1*4)=152
152 % 10 = 2
So 38819-44-2 is a valid CAS Registry Number.

Joseph, John M.,Nes, William R.
, p. 367 - 368 (1981)
The (20R)- and (20S)-epimers of halosterol, a naturally occurring C26-analogue of cholesterol, have been synthesized; the (20R)-epimer was identical with and the (20S)-epimer different from the sterol derived from the naturally occurring 22-dehydro derivative.
