73556-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73556-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,5 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73556-52:
(7*7)+(6*3)+(5*5)+(4*5)+(3*6)+(2*5)+(1*2)=142
142 % 10 = 2
So 73556-52-2 is a valid CAS Registry Number.
