1309870-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309870-81-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,7 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1309870-81:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*7)+(3*0)+(2*8)+(1*1)=172
172 % 10 = 2
So 1309870-81-2 is a valid CAS Registry Number.
