931973-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 931973-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,1,9,7 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 931973-53:
(8*9)+(7*3)+(6*1)+(5*9)+(4*7)+(3*3)+(2*5)+(1*3)=194
194 % 10 = 4
So 931973-53-4 is a valid CAS Registry Number.
