28181-39-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28181-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,8 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28181-39:
(7*2)+(6*8)+(5*1)+(4*8)+(3*1)+(2*3)+(1*9)=117
117 % 10 = 7
So 28181-39-7 is a valid CAS Registry Number.
