667908-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 667908-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,9,0 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 667908-87:
(8*6)+(7*6)+(6*7)+(5*9)+(4*0)+(3*8)+(2*8)+(1*7)=224
224 % 10 = 4
So 667908-87-4 is a valid CAS Registry Number.
