119867-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119867-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119867-67:
(8*1)+(7*1)+(6*9)+(5*8)+(4*6)+(3*7)+(2*6)+(1*7)=173
173 % 10 = 3
So 119867-67-3 is a valid CAS Registry Number.
