119020-41-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119020-41-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,2 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119020-41:
(8*1)+(7*1)+(6*9)+(5*0)+(4*2)+(3*0)+(2*4)+(1*1)=86
86 % 10 = 6
So 119020-41-6 is a valid CAS Registry Number.
