138832-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138832-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138832-99:
(8*1)+(7*3)+(6*8)+(5*8)+(4*3)+(3*2)+(2*9)+(1*9)=162
162 % 10 = 2
So 138832-99-2 is a valid CAS Registry Number.
