151859-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151859-08-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,8,5 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 151859-08:
(8*1)+(7*5)+(6*1)+(5*8)+(4*5)+(3*9)+(2*0)+(1*8)=144
144 % 10 = 4
So 151859-08-4 is a valid CAS Registry Number.
