1309888-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309888-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,8 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1309888-91:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*8)+(3*8)+(2*9)+(1*1)=202
202 % 10 = 2
So 1309888-91-2 is a valid CAS Registry Number.
