73962-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73962-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,6 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73962-85:
(7*7)+(6*3)+(5*9)+(4*6)+(3*2)+(2*8)+(1*5)=163
163 % 10 = 3
So 73962-85-3 is a valid CAS Registry Number.
