138588-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138588-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,8 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138588-54:
(8*1)+(7*3)+(6*8)+(5*5)+(4*8)+(3*8)+(2*5)+(1*4)=172
172 % 10 = 2
So 138588-54-2 is a valid CAS Registry Number.
