Check Digit Verification of cas no
The CAS Registry Mumber 239-85-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,3 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 239-85:
(5*2)+(4*3)+(3*9)+(2*8)+(1*5)=70
70 % 10 = 0
So 239-85-0 is a valid CAS Registry Number.
