87318-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87318-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,3,1 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87318-98:
(7*8)+(6*7)+(5*3)+(4*1)+(3*8)+(2*9)+(1*8)=167
167 % 10 = 7
So 87318-98-7 is a valid CAS Registry Number.
