The CAS Registry Mumber 925-70-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 5 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 925-70: (5*9)+(4*2)+(3*5)+(2*7)+(1*0)=82 82 % 10 = 2 So 925-70-2 is a valid CAS Registry Number.
