1252012-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1252012-51-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,0,1 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1252012-51:
(9*1)+(8*2)+(7*5)+(6*2)+(5*0)+(4*1)+(3*2)+(2*5)+(1*1)=93
93 % 10 = 3
So 1252012-51-3 is a valid CAS Registry Number.
