77481-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77481-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,8 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77481-73:
(7*7)+(6*7)+(5*4)+(4*8)+(3*1)+(2*7)+(1*3)=163
163 % 10 = 3
So 77481-73-3 is a valid CAS Registry Number.
