Check Digit Verification of cas no
The CAS Registry Mumber 9008-42-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively. Calculate Digit Verification of CAS Registry Number 9008-42: (6*9)+(5*0)+(4*0)+(3*8)+(2*4)+(1*2)=88 88 % 10 = 8 So 9008-42-8 is a valid CAS Registry Number.
