72906-45-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72906-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,0 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72906-45:
(7*7)+(6*2)+(5*9)+(4*0)+(3*6)+(2*4)+(1*5)=137
137 % 10 = 7
So 72906-45-7 is a valid CAS Registry Number.
