Check Digit Verification of cas no
The CAS Registry Mumber 1509927-87-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,0,9,9,2 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1509927-87:
(9*1)+(8*5)+(7*0)+(6*9)+(5*9)+(4*2)+(3*7)+(2*8)+(1*7)=200
200 % 10 = 0
So 1509927-87-0 is a valid CAS Registry Number.
