The CAS Registry Mumber 1372149-01-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,1,4 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1372149-01:
(9*1)+(8*3)+(7*7)+(6*2)+(5*1)+(4*4)+(3*9)+(2*0)+(1*1)=143
143 % 10 = 3
So 1372149-01-3 is a valid CAS Registry Number.
