71808-85-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71808-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,0 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71808-85:
(7*7)+(6*1)+(5*8)+(4*0)+(3*8)+(2*8)+(1*5)=140
140 % 10 = 0
So 71808-85-0 is a valid CAS Registry Number.
