87506-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87506-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,0 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87506-01:
(7*8)+(6*7)+(5*5)+(4*0)+(3*6)+(2*0)+(1*1)=142
142 % 10 = 2
So 87506-01-2 is a valid CAS Registry Number.
