280137-62-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 280137-62-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,1,3 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 280137-62:
(8*2)+(7*8)+(6*0)+(5*1)+(4*3)+(3*7)+(2*6)+(1*2)=124
124 % 10 = 4
So 280137-62-4 is a valid CAS Registry Number.
