138713-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138713-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,1 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138713-81:
(8*1)+(7*3)+(6*8)+(5*7)+(4*1)+(3*3)+(2*8)+(1*1)=142
142 % 10 = 2
So 138713-81-2 is a valid CAS Registry Number.
