249928-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 249928-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,9,2 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 249928-52:
(8*2)+(7*4)+(6*9)+(5*9)+(4*2)+(3*8)+(2*5)+(1*2)=187
187 % 10 = 7
So 249928-52-7 is a valid CAS Registry Number.
