70840-44-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70840-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,4 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70840-44:
(7*7)+(6*0)+(5*8)+(4*4)+(3*0)+(2*4)+(1*4)=117
117 % 10 = 7
So 70840-44-7 is a valid CAS Registry Number.
