Check Digit Verification of cas no
The CAS Registry Mumber 851915-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,9,1 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 851915-13:
(8*8)+(7*5)+(6*1)+(5*9)+(4*1)+(3*5)+(2*1)+(1*3)=174
174 % 10 = 4
