824-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 824-87-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 824-87:
(5*8)+(4*2)+(3*4)+(2*8)+(1*7)=83
83 % 10 = 3
