138034-80-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138034-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,3 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138034-80:
(8*1)+(7*3)+(6*8)+(5*0)+(4*3)+(3*4)+(2*8)+(1*0)=117
117 % 10 = 7
So 138034-80-7 is a valid CAS Registry Number.
