1413926-17-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1413926-17-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,3,9,2 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1413926-17:
(9*1)+(8*4)+(7*1)+(6*3)+(5*9)+(4*2)+(3*6)+(2*1)+(1*7)=146
146 % 10 = 6
So 1413926-17-6 is a valid CAS Registry Number.
