Check Digit Verification of cas no
The CAS Registry Mumber 1445772-45-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,5,7,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1445772-45:
(9*1)+(8*4)+(7*4)+(6*5)+(5*7)+(4*7)+(3*2)+(2*4)+(1*5)=181
181 % 10 = 1
So 1445772-45-1 is a valid CAS Registry Number.
