102104-16-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102104-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,1,0 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102104-16:
(8*1)+(7*0)+(6*2)+(5*1)+(4*0)+(3*4)+(2*1)+(1*6)=45
45 % 10 = 5
So 102104-16-5 is a valid CAS Registry Number.
