73720-15-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73720-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,2 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73720-15:
(7*7)+(6*3)+(5*7)+(4*2)+(3*0)+(2*1)+(1*5)=117
117 % 10 = 7
So 73720-15-7 is a valid CAS Registry Number.
