Check Digit Verification of cas no

The CAS Registry Mumber 49723-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,2 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 49723-76:
(7*4)+(6*9)+(5*7)+(4*2)+(3*3)+(2*7)+(1*6)=154
154 % 10 = 4
So 49723-76-4 is a valid CAS Registry Number.

Spectral observation of conversion between ionized vs. non-ionized proton-coupled electron transfer interfaces

Young, Elizabeth R.,Rosenthal, Joel,Nocera, Daniel G.

, p. 2322 - 2324 (2008)

Two-point hydrogen bonding between acid and base functionalities provides a convenient method for the modular assembly of proton-coupled electron transfer (PCET) networks, especially when that interface comprises an amidinium and two-point anionic partner; a system is presented that permits the proton configuration within the interface to be determined when pKa values of the conjugate acids are known.
