138002-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138002-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,0 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138002-56:
(8*1)+(7*3)+(6*8)+(5*0)+(4*0)+(3*2)+(2*5)+(1*6)=99
99 % 10 = 9
So 138002-56-9 is a valid CAS Registry Number.
