Check Digit Verification of cas no
The CAS Registry Mumber 519186-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,9,1,8 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 519186-55:
(8*5)+(7*1)+(6*9)+(5*1)+(4*8)+(3*6)+(2*5)+(1*5)=171
171 % 10 = 1
So 519186-55-1 is a valid CAS Registry Number.
