Check Digit Verification of cas no
The CAS Registry Mumber 935398-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,5,3,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 935398-20:
(8*9)+(7*3)+(6*5)+(5*3)+(4*9)+(3*8)+(2*2)+(1*0)=202
202 % 10 = 2
So 935398-20-2 is a valid CAS Registry Number.
