854642-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 854642-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,4,6,4 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 854642-62:
(8*8)+(7*5)+(6*4)+(5*6)+(4*4)+(3*2)+(2*6)+(1*2)=189
189 % 10 = 9
So 854642-62-9 is a valid CAS Registry Number.
