320748-74-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 320748-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,0,7,4 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 320748-74:
(8*3)+(7*2)+(6*0)+(5*7)+(4*4)+(3*8)+(2*7)+(1*4)=131
131 % 10 = 1
So 320748-74-1 is a valid CAS Registry Number.
