Check Digit Verification of cas no
The CAS Registry Mumber 248253-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,8,2,5 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 248253-35:
(8*2)+(7*4)+(6*8)+(5*2)+(4*5)+(3*3)+(2*3)+(1*5)=142
142 % 10 = 2
So 248253-35-2 is a valid CAS Registry Number.
