13659-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13659-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,5 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13659-18:
(7*1)+(6*3)+(5*6)+(4*5)+(3*9)+(2*1)+(1*8)=112
112 % 10 = 2
So 13659-18-2 is a valid CAS Registry Number.
