119962-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119962-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,6 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119962-89:
(8*1)+(7*1)+(6*9)+(5*9)+(4*6)+(3*2)+(2*8)+(1*9)=169
169 % 10 = 9
So 119962-89-9 is a valid CAS Registry Number.
