Check Digit Verification of cas no
The CAS Registry Mumber 150057-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,0,5 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 150057-00:
(8*1)+(7*5)+(6*0)+(5*0)+(4*5)+(3*7)+(2*0)+(1*0)=84
84 % 10 = 4
So 150057-00-4 is a valid CAS Registry Number.
