87223-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87223-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,2 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87223-67:
(7*8)+(6*7)+(5*2)+(4*2)+(3*3)+(2*6)+(1*7)=144
144 % 10 = 4
So 87223-67-4 is a valid CAS Registry Number.
