Check Digit Verification of cas no

The CAS Registry Mumber 25825-59-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,2 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25825-59:
(7*2)+(6*5)+(5*8)+(4*2)+(3*5)+(2*5)+(1*9)=126
126 % 10 = 6
So 25825-59-6 is a valid CAS Registry Number.

TRIS(3,6-DIOXAHEPTYL)AMINE: A SUPERIOR COMPLEXING AGENT FOR DISSOLVING METAL REACTIONS

Bose, Ajay K.,Mangiaracina, Pietro

, p. 2503 - 2506 (2007/10/02)

Commercially available tris(3,6-dioxaheptyl)amine (TDA-1) is an effective phase transfer catalyst for reactions with sodium-potassium alloy in tetrahydrofuran.Deoxygenation of acetates, dehalogenation, and hydrolysis of tosylates and mesylates proceed in high yield.The use of a deuterated alcohol during deoxygenation reactions leads to site-specific deuteration.
