135489-71-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135489-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,8 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135489-71:
(8*1)+(7*3)+(6*5)+(5*4)+(4*8)+(3*9)+(2*7)+(1*1)=153
153 % 10 = 3
So 135489-71-3 is a valid CAS Registry Number.
