138458-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138458-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138458-33:
(8*1)+(7*3)+(6*8)+(5*4)+(4*5)+(3*8)+(2*3)+(1*3)=150
150 % 10 = 0
So 138458-33-0 is a valid CAS Registry Number.
