802902-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 802902-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,2,9,0 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 802902-74:
(8*8)+(7*0)+(6*2)+(5*9)+(4*0)+(3*2)+(2*7)+(1*4)=145
145 % 10 = 5
So 802902-74-5 is a valid CAS Registry Number.
