21-Formil-Δ5,16-pregnadien-3β-ol-20-one-dimethylacetale is a complex organic compound belonging to the steroid family. It is characterized by a pregnane core structure, which is a type of steroid with a cyclohexane ring fused to a cyclopentane ring. The compound features a 3β-hydroxyl group, indicating the presence of a hydroxyl group at the 3-position on the steroid nucleus. Additionally, it has a formyl group (aldehyde) at the 21-position and a Δ5,16 double bond, which refers to the presence of a double bond between carbons 5 and 6, and another between carbons 16 and 17. The dimethyl acetal functional group suggests that two hydroxyl groups are protected by a methyl group, forming an acetal. 21-Formil-Δ^5,16-pregnadien-3β-ol-20-one-dimethylacetale is likely to be found in pharmaceutical or chemical research settings, potentially as an intermediate in the synthesis of other steroidal compounds or as a precursor in the production of hormones or other biologically active substances.

Check Digit Verification of cas no

The CAS Registry Mumber 1805-07-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1805-07:
(6*1)+(5*8)+(4*0)+(3*5)+(2*0)+(1*7)=68
68 % 10 = 8
So 1805-07-8 is a valid CAS Registry Number.
