Check Digit Verification of cas no
The CAS Registry Mumber 41306-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,3,0 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 41306-28:
(7*4)+(6*1)+(5*3)+(4*0)+(3*6)+(2*2)+(1*8)=79
79 % 10 = 9
