67508-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67508-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,0 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67508-85:
(7*6)+(6*7)+(5*5)+(4*0)+(3*8)+(2*8)+(1*5)=154
154 % 10 = 4
So 67508-85-4 is a valid CAS Registry Number.
