138515-32-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138515-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,1 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138515-32:
(8*1)+(7*3)+(6*8)+(5*5)+(4*1)+(3*5)+(2*3)+(1*2)=129
129 % 10 = 9
So 138515-32-9 is a valid CAS Registry Number.
