1431638-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431638-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,6,3 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1431638-89:
(9*1)+(8*4)+(7*3)+(6*1)+(5*6)+(4*3)+(3*8)+(2*8)+(1*9)=159
159 % 10 = 9
So 1431638-89-9 is a valid CAS Registry Number.
