Check Digit Verification of cas no
The CAS Registry Mumber 187227-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,2,2 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 187227-07:
(8*1)+(7*8)+(6*7)+(5*2)+(4*2)+(3*7)+(2*0)+(1*7)=152
152 % 10 = 2
So 187227-07-2 is a valid CAS Registry Number.
