3749-38-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3749-38-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,4 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3749-38:
(6*3)+(5*7)+(4*4)+(3*9)+(2*3)+(1*8)=110
110 % 10 = 0
So 3749-38-0 is a valid CAS Registry Number.

Siroxylin derivative and application thereof

-

Paragraph 0034-0039, (2021/05/08)

The invention provides a daphnoretin derivative and application thereof. The daphnoretin derivative or a stereoisomer, hydrate, ester, solvate, eutectic, metabolite and pharmaceutically accepted saltor prodrug of the daphnoretin derivative has good anti-tumor activity, the anti-tumor activity of the daphnoretin derivative is obviously better than that of daphnoretin, and the daphnoretin derivative can be used as a novel efficient low-toxicity anti-tumor drug.
