Check Digit Verification of cas no
The CAS Registry Mumber 68554-70-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,5 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.Calculate Digit Verification of CAS Registry Number 68554-70:
(7*6)+(6*8)+(5*5)+(4*5)+(3*4)+(2*7)+(1*0)=161
161 % 10 = 1
So 68554-70-1 is a valid CAS Registry Number.
