Check Digit Verification of cas no
The CAS Registry Mumber 127503-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,0 and 3 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 127503-04: (8*1)+(7*2)+(6*7)+(5*5)+(4*0)+(3*3)+(2*0)+(1*4)=102 102 % 10 = 2 So 127503-04-2 is a valid CAS Registry Number.
