Check Digit Verification of cas no
The CAS Registry Mumber 391860-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,8,6 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 391860-55:
(8*3)+(7*9)+(6*1)+(5*8)+(4*6)+(3*0)+(2*5)+(1*5)=172
172 % 10 = 2
So 391860-55-2 is a valid CAS Registry Number.
