Check Digit Verification of cas no
The CAS Registry Mumber 1332640-89-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,2,6,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1332640-89:
(9*1)+(8*3)+(7*3)+(6*2)+(5*6)+(4*4)+(3*0)+(2*8)+(1*9)=137
137 % 10 = 7
So 1332640-89-7 is a valid CAS Registry Number.
