72187-06-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72187-06-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,8 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 72187-06:
(7*7)+(6*2)+(5*1)+(4*8)+(3*7)+(2*0)+(1*6)=125
125 % 10 = 5
So 72187-06-5 is a valid CAS Registry Number.
