69140-06-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69140-06-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,1,4 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69140-06:
(7*6)+(6*9)+(5*1)+(4*4)+(3*0)+(2*0)+(1*6)=123
123 % 10 = 3
So 69140-06-3 is a valid CAS Registry Number.

Hedtmann, Udo,Hobert, Kurt,Milkova, Tsenka,Welzel, Peter
, p. 1941 - 1952 (2007/10/02)
Two routes for the conversion of 5α-cholest-7-ene-3β-ol (11) into 7, which has the typical ecdysteroid substitution pattern in rings B, C, and D, have been developed.Making use of one of the methods, 5,6-dihydroergosterol (31) was converted into the 38, p
