431990-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 431990-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,9,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 431990-78:
(8*4)+(7*3)+(6*1)+(5*9)+(4*9)+(3*0)+(2*7)+(1*8)=162
162 % 10 = 2
So 431990-78-2 is a valid CAS Registry Number.
