73307-38-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73307-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,0 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73307-38:
(7*7)+(6*3)+(5*3)+(4*0)+(3*7)+(2*3)+(1*8)=117
117 % 10 = 7
So 73307-38-7 is a valid CAS Registry Number.
