139259-36-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139259-36-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,5 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139259-36:
(8*1)+(7*3)+(6*9)+(5*2)+(4*5)+(3*9)+(2*3)+(1*6)=152
152 % 10 = 2
So 139259-36-2 is a valid CAS Registry Number.
