471253-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 471253-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,1,2,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 471253-40:
(8*4)+(7*7)+(6*1)+(5*2)+(4*5)+(3*3)+(2*4)+(1*0)=134
134 % 10 = 4
So 471253-40-4 is a valid CAS Registry Number.
