136787-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136787-98-9 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, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136787-98:
(8*1)+(7*3)+(6*6)+(5*7)+(4*8)+(3*7)+(2*9)+(1*8)=179
179 % 10 = 9
So 136787-98-9 is a valid CAS Registry Number.
