The CAS Registry Mumber 1336907-32-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,6,9,0 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1336907-32:
(9*1)+(8*3)+(7*3)+(6*6)+(5*9)+(4*0)+(3*7)+(2*3)+(1*2)=164
164 % 10 = 4
So 1336907-32-4 is a valid CAS Registry Number.
