Check Digit Verification of cas no
The CAS Registry Mumber 421558-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,1,5,5 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 421558-10:
(8*4)+(7*2)+(6*1)+(5*5)+(4*5)+(3*8)+(2*1)+(1*0)=123
123 % 10 = 3
So 421558-10-3 is a valid CAS Registry Number.
