Check Digit Verification of cas no
The CAS Registry Mumber 88522-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,5,2 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 88522-30:
(7*8)+(6*8)+(5*5)+(4*2)+(3*2)+(2*3)+(1*0)=149
149 % 10 = 9
