Check Digit Verification of cas no
The CAS Registry Mumber 907217-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,7,2,1 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 907217-45:
(8*9)+(7*0)+(6*7)+(5*2)+(4*1)+(3*7)+(2*4)+(1*5)=162
162 % 10 = 2
So 907217-45-2 is a valid CAS Registry Number.
