Check Digit Verification of cas no
The CAS Registry Mumber 188559-03-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,5 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188559-03:
(8*1)+(7*8)+(6*8)+(5*5)+(4*5)+(3*9)+(2*0)+(1*3)=187
187 % 10 = 7
