1413926-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1413926-19-8 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 1413926-19:
(9*1)+(8*4)+(7*1)+(6*3)+(5*9)+(4*2)+(3*6)+(2*1)+(1*9)=148
148 % 10 = 8
So 1413926-19-8 is a valid CAS Registry Number.
