78693-53-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78693-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,9 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78693-53:
(7*7)+(6*8)+(5*6)+(4*9)+(3*3)+(2*5)+(1*3)=185
185 % 10 = 5
So 78693-53-5 is a valid CAS Registry Number.
