72216-45-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72216-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,1 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72216-45:
(7*7)+(6*2)+(5*2)+(4*1)+(3*6)+(2*4)+(1*5)=106
106 % 10 = 6
So 72216-45-6 is a valid CAS Registry Number.
