Check Digit Verification of cas no
The CAS Registry Mumber 89091-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89091-72:
(7*8)+(6*9)+(5*0)+(4*9)+(3*1)+(2*7)+(1*2)=165
165 % 10 = 5
