139269-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139269-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,6 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139269-26:
(8*1)+(7*3)+(6*9)+(5*2)+(4*6)+(3*9)+(2*2)+(1*6)=154
154 % 10 = 4
So 139269-26-4 is a valid CAS Registry Number.
