Check Digit Verification of cas no
The CAS Registry Mumber 63148-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,4 and 8 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 63148-64: (7*6)+(6*3)+(5*1)+(4*4)+(3*8)+(2*6)+(1*4)=121 121 % 10 = 1 So 63148-64-1 is a valid CAS Registry Number.
