1290538-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1290538-39-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,5,3 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1290538-39:
(9*1)+(8*2)+(7*9)+(6*0)+(5*5)+(4*3)+(3*8)+(2*3)+(1*9)=164
164 % 10 = 4
So 1290538-39-4 is a valid CAS Registry Number.
