72718-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72718-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,1 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72718-61:
(7*7)+(6*2)+(5*7)+(4*1)+(3*8)+(2*6)+(1*1)=137
137 % 10 = 7
So 72718-61-7 is a valid CAS Registry Number.
