1252041-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1252041-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,0,4 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1252041-52:
(9*1)+(8*2)+(7*5)+(6*2)+(5*0)+(4*4)+(3*1)+(2*5)+(1*2)=103
103 % 10 = 3
So 1252041-52-3 is a valid CAS Registry Number.
