Check Digit Verification of cas no
The CAS Registry Mumber 118997-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,9 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118997-30:
(8*1)+(7*1)+(6*8)+(5*9)+(4*9)+(3*7)+(2*3)+(1*0)=171
171 % 10 = 1
So 118997-30-1 is a valid CAS Registry Number.
