845640-44-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 845640-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,6,4 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 845640-44:
(8*8)+(7*4)+(6*5)+(5*6)+(4*4)+(3*0)+(2*4)+(1*4)=180
180 % 10 = 0
So 845640-44-0 is a valid CAS Registry Number.
