Check Digit Verification of cas no
The CAS Registry Mumber 871700-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,7,0 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 871700-49:
(8*8)+(7*7)+(6*1)+(5*7)+(4*0)+(3*0)+(2*4)+(1*9)=171
171 % 10 = 1
So 871700-49-1 is a valid CAS Registry Number.
