1609929-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1609929-58-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,9,2 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1609929-58:
(9*1)+(8*6)+(7*0)+(6*9)+(5*9)+(4*2)+(3*9)+(2*5)+(1*8)=209
209 % 10 = 9
So 1609929-58-9 is a valid CAS Registry Number.
