16890-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16890-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,9 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16890-71:
(7*1)+(6*6)+(5*8)+(4*9)+(3*0)+(2*7)+(1*1)=134
134 % 10 = 4
So 16890-71-4 is a valid CAS Registry Number.
