Check Digit Verification of cas no
The CAS Registry Mumber 873203-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,2,0 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 873203-77:
(8*8)+(7*7)+(6*3)+(5*2)+(4*0)+(3*3)+(2*7)+(1*7)=171
171 % 10 = 1
So 873203-77-1 is a valid CAS Registry Number.
