138175-64-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138175-64-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,7 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138175-64:
(8*1)+(7*3)+(6*8)+(5*1)+(4*7)+(3*5)+(2*6)+(1*4)=141
141 % 10 = 1
So 138175-64-1 is a valid CAS Registry Number.
