Check Digit Verification of cas no
The CAS Registry Mumber 81805-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,0 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81805-55:
(7*8)+(6*1)+(5*8)+(4*0)+(3*5)+(2*5)+(1*5)=132
132 % 10 = 2
