Check Digit Verification of cas no
The CAS Registry Mumber 248920-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,8,9,2 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 248920-01:
(8*2)+(7*4)+(6*8)+(5*9)+(4*2)+(3*0)+(2*0)+(1*1)=146
146 % 10 = 6
So 248920-01-6 is a valid CAS Registry Number.
