119841-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119841-65-5 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 119841-65:
(8*1)+(7*1)+(6*9)+(5*8)+(4*4)+(3*1)+(2*6)+(1*5)=145
145 % 10 = 5
So 119841-65-5 is a valid CAS Registry Number.
