149457-48-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149457-48-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 149457-48:
(8*1)+(7*4)+(6*9)+(5*4)+(4*5)+(3*7)+(2*4)+(1*8)=167
167 % 10 = 7
So 149457-48-7 is a valid CAS Registry Number.
