946435-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 946435-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,6,4,3 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 946435-98:
(8*9)+(7*4)+(6*6)+(5*4)+(4*3)+(3*5)+(2*9)+(1*8)=209
209 % 10 = 9
So 946435-98-9 is a valid CAS Registry Number.
