452920-27-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 452920-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,9,2 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 452920-27:
(8*4)+(7*5)+(6*2)+(5*9)+(4*2)+(3*0)+(2*2)+(1*7)=143
143 % 10 = 3
So 452920-27-3 is a valid CAS Registry Number.
