81850-32-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81850-32-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,5 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81850-32:
(7*8)+(6*1)+(5*8)+(4*5)+(3*0)+(2*3)+(1*2)=130
130 % 10 = 0
So 81850-32-0 is a valid CAS Registry Number.
