Check Digit Verification of cas no
The CAS Registry Mumber 89880-47-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,8 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89880-47:
(7*8)+(6*9)+(5*8)+(4*8)+(3*0)+(2*4)+(1*7)=197
197 % 10 = 7
So 89880-47-7 is a valid CAS Registry Number.
