The CAS Registry Mumber 1372157-33-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,1,5 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1372157-33:
(9*1)+(8*3)+(7*7)+(6*2)+(5*1)+(4*5)+(3*7)+(2*3)+(1*3)=149
149 % 10 = 9
