Check Digit Verification of cas no
The CAS Registry Mumber 151049-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,0,4 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 151049-77:
(8*1)+(7*5)+(6*1)+(5*0)+(4*4)+(3*9)+(2*7)+(1*7)=113
113 % 10 = 3
So 151049-77-3 is a valid CAS Registry Number.
