1431621-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431621-26-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,6,2 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1431621-26:
(9*1)+(8*4)+(7*3)+(6*1)+(5*6)+(4*2)+(3*1)+(2*2)+(1*6)=119
119 % 10 = 9
So 1431621-26-9 is a valid CAS Registry Number.
