72223-51-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72223-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,2 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72223-51:
(7*7)+(6*2)+(5*2)+(4*2)+(3*3)+(2*5)+(1*1)=99
99 % 10 = 9
So 72223-51-9 is a valid CAS Registry Number.
