213549-51-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213549-51-0 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 213549-51:
(8*2)+(7*1)+(6*3)+(5*5)+(4*4)+(3*9)+(2*5)+(1*1)=120
120 % 10 = 0
So 213549-51-0 is a valid CAS Registry Number.
