1305287-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1305287-72-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,5,2,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1305287-72:
(9*1)+(8*3)+(7*0)+(6*5)+(5*2)+(4*8)+(3*7)+(2*7)+(1*2)=142
142 % 10 = 2
So 1305287-72-2 is a valid CAS Registry Number.
