119868-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119868-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,6 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119868-31:
(8*1)+(7*1)+(6*9)+(5*8)+(4*6)+(3*8)+(2*3)+(1*1)=164
164 % 10 = 4
So 119868-31-4 is a valid CAS Registry Number.
