The CAS Registry Mumber 70562-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,6 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70562-37:
(7*7)+(6*0)+(5*5)+(4*6)+(3*2)+(2*3)+(1*7)=117
117 % 10 = 7
