119841-62-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119841-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,4 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 119841-62:
(8*1)+(7*1)+(6*9)+(5*8)+(4*4)+(3*1)+(2*6)+(1*2)=142
142 % 10 = 2
So 119841-62-2 is a valid CAS Registry Number.
