87817-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87817-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,1 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87817-18:
(7*8)+(6*7)+(5*8)+(4*1)+(3*7)+(2*1)+(1*8)=173
173 % 10 = 3
So 87817-18-3 is a valid CAS Registry Number.
