213549-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213549-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,5,4 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213549-53:
(8*2)+(7*1)+(6*3)+(5*5)+(4*4)+(3*9)+(2*5)+(1*3)=122
122 % 10 = 2
So 213549-53-2 is a valid CAS Registry Number.
