87703-00-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87703-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,0 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87703-00:
(7*8)+(6*7)+(5*7)+(4*0)+(3*3)+(2*0)+(1*0)=142
142 % 10 = 2
So 87703-00-2 is a valid CAS Registry Number.
