Check Digit Verification of cas no
The CAS Registry Mumber 1502654-87-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,0,2,6,5 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1502654-87:
(9*1)+(8*5)+(7*0)+(6*2)+(5*6)+(4*5)+(3*4)+(2*8)+(1*7)=146
146 % 10 = 6
So 1502654-87-6 is a valid CAS Registry Number.
