1312889-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312889-69-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,8,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1312889-69:
(9*1)+(8*3)+(7*1)+(6*2)+(5*8)+(4*8)+(3*9)+(2*6)+(1*9)=172
172 % 10 = 2
So 1312889-69-2 is a valid CAS Registry Number.
