Check Digit Verification of cas no
The CAS Registry Mumber 420121-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,1,2 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 420121-01:
(8*4)+(7*2)+(6*0)+(5*1)+(4*2)+(3*1)+(2*0)+(1*1)=63
63 % 10 = 3
So 420121-01-3 is a valid CAS Registry Number.
