149338-12-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149338-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,3,3 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149338-12:
(8*1)+(7*4)+(6*9)+(5*3)+(4*3)+(3*8)+(2*1)+(1*2)=145
145 % 10 = 5
So 149338-12-5 is a valid CAS Registry Number.
