331002-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 331002-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,0,0 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 331002-74:
(8*3)+(7*3)+(6*1)+(5*0)+(4*0)+(3*2)+(2*7)+(1*4)=75
75 % 10 = 5
So 331002-74-5 is a valid CAS Registry Number.
