Check Digit Verification of cas no
The CAS Registry Mumber 21857-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,5 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.Calculate Digit Verification of CAS Registry Number 21857-40:
(7*2)+(6*1)+(5*8)+(4*5)+(3*7)+(2*4)+(1*0)=109
109 % 10 = 9
So 21857-40-9 is a valid CAS Registry Number.
