The CAS Registry Mumber 377075-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,7,0,7 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 377075-27:
(8*3)+(7*7)+(6*7)+(5*0)+(4*7)+(3*5)+(2*2)+(1*7)=169
169 % 10 = 9
