Check Digit Verification of cas no
The CAS Registry Mumber 117377-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,3,7 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117377-53:
(8*1)+(7*1)+(6*7)+(5*3)+(4*7)+(3*7)+(2*5)+(1*3)=134
134 % 10 = 4
So 117377-53-4 is a valid CAS Registry Number.
