1220687-95-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1220687-95-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,6,8 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1220687-95:
(9*1)+(8*2)+(7*2)+(6*0)+(5*6)+(4*8)+(3*7)+(2*9)+(1*5)=145
145 % 10 = 5
So 1220687-95-5 is a valid CAS Registry Number.
