1399697-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1399697-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,6,9 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1399697-89:
(9*1)+(8*3)+(7*9)+(6*9)+(5*6)+(4*9)+(3*7)+(2*8)+(1*9)=262
262 % 10 = 2
So 1399697-89-2 is a valid CAS Registry Number.
