The CAS Registry Mumber 131822-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,2 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131822-52:
(8*1)+(7*3)+(6*1)+(5*8)+(4*2)+(3*2)+(2*5)+(1*2)=101
101 % 10 = 1
So 131822-52-1 is a valid CAS Registry Number.
