Check Digit Verification of cas no
The CAS Registry Mumber 133637-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,3 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133637-98:
(8*1)+(7*3)+(6*3)+(5*6)+(4*3)+(3*7)+(2*9)+(1*8)=136
136 % 10 = 6
So 133637-98-6 is a valid CAS Registry Number.
