642485-84-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 642485-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,4,8 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 642485-84:
(8*6)+(7*4)+(6*2)+(5*4)+(4*8)+(3*5)+(2*8)+(1*4)=175
175 % 10 = 5
So 642485-84-5 is a valid CAS Registry Number.
