1419181-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1419181-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,9,1,8 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1419181-99:
(9*1)+(8*4)+(7*1)+(6*9)+(5*1)+(4*8)+(3*1)+(2*9)+(1*9)=169
169 % 10 = 9
So 1419181-99-9 is a valid CAS Registry Number.
