72687-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72687-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72687-01:
(7*7)+(6*2)+(5*6)+(4*8)+(3*7)+(2*0)+(1*1)=145
145 % 10 = 5
So 72687-01-5 is a valid CAS Registry Number.
