320722-51-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 320722-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,0,7,2 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 320722-51:
(8*3)+(7*2)+(6*0)+(5*7)+(4*2)+(3*2)+(2*5)+(1*1)=98
98 % 10 = 8
So 320722-51-8 is a valid CAS Registry Number.

Disulfide-strapped porphyrins for monolayer formation on gold
Redman, James E.,Sanders, Jeremy K. M.
, p. 4141 - 4144 (2000)
(equation presented) M = 2H, Zn; R = n - hexyl Porphyrins with a disulfide-containing strap have been prepared as an alternative to dithiols for self-assembled monolayer formation on gold surfaces. The strapped porphyrins have the advantage of greater air
