Check Digit Verification of cas no
The CAS Registry Mumber 109775-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,7 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109775-01:
(8*1)+(7*0)+(6*9)+(5*7)+(4*7)+(3*5)+(2*0)+(1*1)=141
141 % 10 = 1
So 109775-01-1 is a valid CAS Registry Number.
