Check Digit Verification of cas no
The CAS Registry Mumber 221524-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,5,2 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221524-06:
(8*2)+(7*2)+(6*1)+(5*5)+(4*2)+(3*4)+(2*0)+(1*6)=87
87 % 10 = 7
So 221524-06-7 is a valid CAS Registry Number.
