138474-53-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138474-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,7 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138474-53:
(8*1)+(7*3)+(6*8)+(5*4)+(4*7)+(3*4)+(2*5)+(1*3)=150
150 % 10 = 0
So 138474-53-0 is a valid CAS Registry Number.
