Check Digit Verification of cas no
The CAS Registry Mumber 168101-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,1,0 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 168101-89:
(8*1)+(7*6)+(6*8)+(5*1)+(4*0)+(3*1)+(2*8)+(1*9)=131
131 % 10 = 1
So 168101-89-1 is a valid CAS Registry Number.
