Check Digit Verification of cas no
The CAS Registry Mumber 68857-84-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,5 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 68857-84:
(7*6)+(6*8)+(5*8)+(4*5)+(3*7)+(2*8)+(1*4)=191
191 % 10 = 1
So 68857-84-1 is a valid CAS Registry Number.
