The chemical "21-Formil-20-(2'-cloro-etossi)-Δ^5,16,20-pregnatrien-3β-olo-acetato" is a complex steroidal compound with a molecular structure characterized by a pregnatrien core, which is a type of steroid with a specific arrangement of carbon atoms. The Δ^5,16,20 notation indicates that there are double bonds between the 5th and 6th, 16th and 17th, and 20th and 21st carbon atoms. The 3β-olo-acetato part of the name suggests that there is an acetate group attached to the 3-beta position of the steroid, and a formyl group (aldehyde) is present at the 21st position. Additionally, a 2'-chloro-ethoxy group is attached at the 20th position, introducing a chlorine atom and an ethoxy chain to the molecule. 21-Formil-20-(2'-cloro-etossi)-Δ^5,16,20-pregnatrien-3β-olo-acetato is likely to be found in the field of pharmaceuticals or biochemistry, where such complex steroidal structures are studied for their potential biological activities and therapeutic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1970-01-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,7 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1970-01:
(6*1)+(5*9)+(4*7)+(3*0)+(2*0)+(1*1)=80
80 % 10 = 0
So 1970-01-0 is a valid CAS Registry Number.
