Check Digit Verification of cas no
The CAS Registry Mumber 89432-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,3 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89432-01:
(7*8)+(6*9)+(5*4)+(4*3)+(3*2)+(2*0)+(1*1)=149
