77533-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77533-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,3 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77533-57:
(7*7)+(6*7)+(5*5)+(4*3)+(3*3)+(2*5)+(1*7)=154
154 % 10 = 4
So 77533-57-4 is a valid CAS Registry Number.
