Check Digit Verification of cas no
The CAS Registry Mumber 105590-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 105590-20:
(8*1)+(7*0)+(6*5)+(5*5)+(4*9)+(3*0)+(2*2)+(1*0)=103
103 % 10 = 3
So 105590-20-3 is a valid CAS Registry Number.
