Check Digit Verification of cas no
The CAS Registry Mumber 1622457-03-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,2,4,5 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1622457-03:
(9*1)+(8*6)+(7*2)+(6*2)+(5*4)+(4*5)+(3*7)+(2*0)+(1*3)=147
147 % 10 = 7
So 1622457-03-7 is a valid CAS Registry Number.
