84955-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84955-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,5 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84955-67:
(7*8)+(6*4)+(5*9)+(4*5)+(3*5)+(2*6)+(1*7)=179
179 % 10 = 9
So 84955-67-9 is a valid CAS Registry Number.
