694452-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 694452-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,4,4,5 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 694452-82:
(8*6)+(7*9)+(6*4)+(5*4)+(4*5)+(3*2)+(2*8)+(1*2)=199
199 % 10 = 9
So 694452-82-9 is a valid CAS Registry Number.
