Check Digit Verification of cas no
The CAS Registry Mumber 156697-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,9 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156697-67:
(8*1)+(7*5)+(6*6)+(5*6)+(4*9)+(3*7)+(2*6)+(1*7)=185
