139214-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139214-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,1 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139214-95:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*4)+(2*9)+(1*5)=132
132 % 10 = 2
So 139214-95-2 is a valid CAS Registry Number.
