The CAS Registry Mumber 640750-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,7,5 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 640750-22:
(8*6)+(7*4)+(6*0)+(5*7)+(4*5)+(3*0)+(2*2)+(1*2)=137
137 % 10 = 7
So 640750-22-7 is a valid CAS Registry Number.
