Check Digit Verification of cas no
The CAS Registry Mumber 136883-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,8 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136883-89:
(8*1)+(7*3)+(6*6)+(5*8)+(4*8)+(3*3)+(2*8)+(1*9)=171
171 % 10 = 1
So 136883-89-1 is a valid CAS Registry Number.
