Check Digit Verification of cas no
The CAS Registry Mumber 117635-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,3 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117635-31:
(8*1)+(7*1)+(6*7)+(5*6)+(4*3)+(3*5)+(2*3)+(1*1)=121
121 % 10 = 1
So 117635-31-1 is a valid CAS Registry Number.
