Check Digit Verification of cas no
The CAS Registry Mumber 420086-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,0,8 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 420086-59:
(8*4)+(7*2)+(6*0)+(5*0)+(4*8)+(3*6)+(2*5)+(1*9)=115
115 % 10 = 5
So 420086-59-5 is a valid CAS Registry Number.
