1418299-52-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1418299-52-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,8,2,9 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1418299-52:
(9*1)+(8*4)+(7*1)+(6*8)+(5*2)+(4*9)+(3*9)+(2*5)+(1*2)=181
181 % 10 = 1
So 1418299-52-1 is a valid CAS Registry Number.
