135473-47-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135473-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,7 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135473-47:
(8*1)+(7*3)+(6*5)+(5*4)+(4*7)+(3*3)+(2*4)+(1*7)=131
131 % 10 = 1
So 135473-47-1 is a valid CAS Registry Number.
