Check Digit Verification of cas no
The CAS Registry Mumber 897017-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,7,0,1 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 897017-11:
(8*8)+(7*9)+(6*7)+(5*0)+(4*1)+(3*7)+(2*1)+(1*1)=197
197 % 10 = 7
So 897017-11-7 is a valid CAS Registry Number.
