Check Digit Verification of cas no
The CAS Registry Mumber 100632-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,6,3 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 100632-58:
(8*1)+(7*0)+(6*0)+(5*6)+(4*3)+(3*2)+(2*5)+(1*8)=74
74 % 10 = 4
So 100632-58-4 is a valid CAS Registry Number.
