66277-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66277-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,7 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66277-12:
(7*6)+(6*6)+(5*2)+(4*7)+(3*7)+(2*1)+(1*2)=141
141 % 10 = 1
So 66277-12-1 is a valid CAS Registry Number.

3-Ethyl and 3-methyl ethers of 19-iodocholesterol as potential adrenal scanning agents.
Owoyale,Szinai
, p. 133 - 141 (1981)
19-Iodocholesterol-131I, though useful as an adrenal scanning agent, was found to be unstable. However, the substitution of methoxyl and ethoxyl groups for the hydroxyl group in the 3 position rendered these derivatives much more stable in solid form than the parent compound. They showed concentration in the adrenals of dogs similar to that of 19-iodocholesterol itself and therefore may be useful as adrenal scanning agents.
