1241950-82-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1241950-82-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,9,5 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1241950-82:
(9*1)+(8*2)+(7*4)+(6*1)+(5*9)+(4*5)+(3*0)+(2*8)+(1*2)=142
142 % 10 = 2
So 1241950-82-2 is a valid CAS Registry Number.
