Check Digit Verification of cas no
The CAS Registry Mumber 85-67-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85-67:
(4*8)+(3*5)+(2*6)+(1*7)=66
66 % 10 = 6
So 85-67-6 is a valid CAS Registry Number.
