139559-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139559-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,5 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139559-70:
(8*1)+(7*3)+(6*9)+(5*5)+(4*5)+(3*9)+(2*7)+(1*0)=169
169 % 10 = 9
So 139559-70-9 is a valid CAS Registry Number.
