1257084-14-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1257084-14-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,0,8 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1257084-14:
(9*1)+(8*2)+(7*5)+(6*7)+(5*0)+(4*8)+(3*4)+(2*1)+(1*4)=152
152 % 10 = 2
So 1257084-14-2 is a valid CAS Registry Number.
