397883-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 397883-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,7,8,8 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 397883-91:
(8*3)+(7*9)+(6*7)+(5*8)+(4*8)+(3*3)+(2*9)+(1*1)=229
229 % 10 = 9
So 397883-91-9 is a valid CAS Registry Number.
