1217504-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1217504-77-2 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, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1217504-77:
(9*1)+(8*2)+(7*1)+(6*7)+(5*5)+(4*0)+(3*4)+(2*7)+(1*7)=132
132 % 10 = 2
So 1217504-77-2 is a valid CAS Registry Number.
