87201-81-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87201-81-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,0 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87201-81:
(7*8)+(6*7)+(5*2)+(4*0)+(3*1)+(2*8)+(1*1)=128
128 % 10 = 8
So 87201-81-8 is a valid CAS Registry Number.
