136787-16-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136787-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,8 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136787-16:
(8*1)+(7*3)+(6*6)+(5*7)+(4*8)+(3*7)+(2*1)+(1*6)=161
161 % 10 = 1
So 136787-16-1 is a valid CAS Registry Number.
