20167-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20167-85-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,6 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20167-85:
(7*2)+(6*0)+(5*1)+(4*6)+(3*7)+(2*8)+(1*5)=85
85 % 10 = 5
