Check Digit Verification of cas no
The CAS Registry Mumber 223675-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,6,7 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 223675-74:
(8*2)+(7*2)+(6*3)+(5*6)+(4*7)+(3*5)+(2*7)+(1*4)=139
139 % 10 = 9
So 223675-74-9 is a valid CAS Registry Number.
