85800-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85800-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,0 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85800-91:
(7*8)+(6*5)+(5*8)+(4*0)+(3*0)+(2*9)+(1*1)=145
145 % 10 = 5
So 85800-91-5 is a valid CAS Registry Number.
