119934-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119934-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,3 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119934-39:
(8*1)+(7*1)+(6*9)+(5*9)+(4*3)+(3*4)+(2*3)+(1*9)=153
153 % 10 = 3
So 119934-39-3 is a valid CAS Registry Number.
