1217504-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217504-87-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,5,0 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1217504-87:
(9*1)+(8*2)+(7*1)+(6*7)+(5*5)+(4*0)+(3*4)+(2*8)+(1*7)=134
134 % 10 = 4
So 1217504-87-4 is a valid CAS Registry Number.
