151258-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151258-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,2,5 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 151258-40:
(8*1)+(7*5)+(6*1)+(5*2)+(4*5)+(3*8)+(2*4)+(1*0)=111
111 % 10 = 1
So 151258-40-1 is a valid CAS Registry Number.
