93316-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93316-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,1 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93316-53:
(7*9)+(6*3)+(5*3)+(4*1)+(3*6)+(2*5)+(1*3)=131
131 % 10 = 1
So 93316-53-1 is a valid CAS Registry Number.
