Check Digit Verification of cas no
The CAS Registry Mumber 70544-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,4 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70544-63:
(7*7)+(6*0)+(5*5)+(4*4)+(3*4)+(2*6)+(1*3)=117
117 % 10 = 7
So 70544-63-7 is a valid CAS Registry Number.
