Check Digit Verification of cas no
The CAS Registry Mumber 566-99-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 566-99:
(5*5)+(4*6)+(3*6)+(2*9)+(1*9)=94
94 % 10 = 4
So 566-99-4 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
