332842-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 332842-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,2,8,4 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 332842-72:
(8*3)+(7*3)+(6*2)+(5*8)+(4*4)+(3*2)+(2*7)+(1*2)=135
135 % 10 = 5
So 332842-72-5 is a valid CAS Registry Number.
