The CAS Registry Mumber 7052-34-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,5 and 2 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7052-34: (6*7)+(5*0)+(4*5)+(3*2)+(2*3)+(1*4)=78 78 % 10 = 8 So 7052-34-8 is a valid CAS Registry Number.
