119887-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119887-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,8 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119887-69:
(8*1)+(7*1)+(6*9)+(5*8)+(4*8)+(3*7)+(2*6)+(1*9)=183
183 % 10 = 3
So 119887-69-3 is a valid CAS Registry Number.
