163840-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163840-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,4 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 163840-13:
(8*1)+(7*6)+(6*3)+(5*8)+(4*4)+(3*0)+(2*1)+(1*3)=129
129 % 10 = 9
So 163840-13-9 is a valid CAS Registry Number.
